+
+ Fix poll_for_response race condition
+
+ In poll_for_response is it possible that event replies are skipped
+ and a more up to date message reply is returned.
+ This will cause next poll_for_event call to fail aborting the program.
+
+ This was proved using some slow ssh tunnel or using some program
+ to slow down server replies (I used a combination of xtrace and strace).
+
+ How the race happens:
+ - program enters into poll_for_response;
+ - poll_for_event is called but the server didn't still send the reply;
+ - pending_requests is not NULL because we send a request (see call
+ to append_pending_request in _XSend);
+ - xcb_poll_for_reply64 is called from poll_for_response;
+ - xcb_poll_for_reply64 will read from server, at this point
+ server reply with an event (say sequence N) and the reply to our
+ last request (say sequence N+1);
+ - xcb_poll_for_reply64 returns the reply for the request we asked;
+ - last_request_read is set to N+1 sequence in poll_for_response;
+ - poll_for_response returns the response to the request;
+ - poll_for_event is called (for instance from another poll_for_response);
+ - event with sequence N is retrieved;
+ - the N sequence is widen, however, as the "new" number computed from
+ last_request_read is less than N the number is widened to N + 2^32
+ (assuming last_request_read is still contained in 32 bit);
+ - poll_for_event enters the nested if statement as req is NULL;
+ - we compare the widen N (which now does not fit into 32 bit) with
+ request (which fits into 32 bit) hitting the throw_thread_fail_assert.
+
+ To avoid the race condition and to avoid the sequence to go back
+ I check again for new events after getting the response and
+ return this last event if present saving the reply to return it
+ later.
+
+ To test the race and the fix it's helpful to add a delay (I used a
+ "usleep(5000)") before calling xcb_poll_for_reply64.

+commit 30ccef3a48029bf4fc31d4abda2d2778d0ad6277
+Author: Keith Packard <keithp%keithp.com@localhost>
+Date: Sat Nov 7 22:22:47 2020 -0800
+
+ Avoid recursing through _XError due to sequence adjustment
+
+ This patch is based on research done by Dmitry Osipenko to uncover the
+ cause of a large class of Xlib lockups.
+
+ _XError must unlock and re-lock the display around the call to the
+ user error handler function. When re-locking the display, two
+ functions are called to ensure that the display is ready to generate a request:
+
+ _XIDHandler(dpy);
+ _XSeqSyncFunction(dpy);
+
+ The first ensures that there is at least one XID available to use
+ (possibly calling _xcb_generate_id to do so). The second makes sure a
+ reply is received at least every 65535 requests to keep sequence
+ numbers in sync (possibly generating a GetInputFocus request and
+ synchronously awaiting the reply).
+
+ If the second of these does generate a GetInputFocus request and wait
+ for the reply, then a pending error will cause recursion into _XError,
+ which deadlocks the display.
+
+ One seemingly easy fix is to have _XError avoid those calls by
+ invoking InternalLockDisplay instead of LockDisplay. That function
+ does everything that LockDisplay does *except* call those final two
+ functions which may end up receiving an error.
+
+ However, that doesn't protect the system from applications which call
+ some legal Xlib function from within their error handler. Any Xlib
+ function which cannot generate protocol or wait for events is valid,
+ including many which invoke LockDisplay.
+
+ What we need to do is make LockDisplay skip these two function calls
+ precisely when it is called from within the _XError context for the
+ same display.
+
+ This patch accomplishes this by creating a list of threads in the
+ display which are in _XError, and then having LockDisplay check the
+ current thread against those list elements.

+ Don't attempt to unload locale context data

+ Most locale context users call _XlcCurrentLC, which returns a pointer
