Subject: Re: lib/30846: problem interrupting select() via signal in a 
 multi-threaded process

 I don't know whether this really the same origin, but there is
 a longstanding problem which makes the selftest of Python-2.4
 hang infinitely.
 There is a test which checks signal delivery. It doesn't use threads
 itself. If I execute it separately, it succeeds without problems. If
 I execute it within the whole selftest suite, it hangs in "sawait"
 forever.
 There is quite a number of other tests in the suite executed before
 that signal check, one of them activating the thread subsystem.
 
 Sorry that I didn't track it down further yet, but this is a
 complex matter and the state of debugging support for threaded
 programs doesn't make it easier.
 
 It can be simply reproduced:
 $ python2.4
 [...]
 >>> from test import autotest
 [proceeds until]
 test_signal
 [hangs]
 
 best regards
