 Sorry, that was way too snarky.
 
 The actual proposition is:
 
 If you panic or assert and drop into ddb, and you know what you're
 doing, and at least in less severe circumstances, it would be nice to
 be able to e.g. force the current lwp to return with an error and
 continue, or just suspend it, in order to be able to do
 sync;sync;reboot.
 
 obviously such a procedure won't always work, but sometimes it will.
 
 jakllsch also says that we currently no longer even attempt to sync
 during panic, which seems wrong.
