Hi all,
I'm hitting a deadlock with cygwin pthreads when joining on a short-lived thread -- for me the second such thread creation will almost never return. It looks *exactly* like a problem that others noticed as far back as early 2005 [0], and from the output of strace on the test case (below) the culprit is almost certainly a racy optimization in __cygwin_lock_* for which a patch was submitted six months ago [1].
As of today my cygwin distribution is completely up to date. Any
hope of an update coming out soon?
The update will be Cygwin 1.7. You testcase works fine for
me on Cygwin 1.7, so maybe you should try this path. See

Thanks, Ryan
