Hi,
found the little scumbag of a bug, after spending all $%^&* day on it.
It's in NSUser.m:579 - the global lock was not being released except in the
exception handler.
The patch:
diff -r1.56 NSUser.m
578a579
> [gnustep_global_lock unlock];
The bug manifested itself by causing the main thread to always hog the first
lock in the NSRecursiveLock. Thus any time any other thread tried to do an
operation requiring gnustep_global_lock locking, it would deadlock.
Bah humbug.
Cheers,
Stephen Brandon
