[perl #114378] cond_signal does not wake up a thread
Message ID:
The bug was indeed in that the joining thread held the lock while the thread being joined waited 
for the same lock in cond_wait. So this is not such a Perl bug, even though the warning that 
cond_wait emits when used on an unlocked variable contributed to the bug, so the Perl 
specification is partly to blame.
