Hi all,

In trying to understand why my application randomly blocks, I found that
it always has 2 threads running and I don't know what the second one is
for.

It seems this thread is waiting on some condition lock :

#0  0xb7fe2424 in __kernel_vsyscall ()
#1  0xb7428015 in pthread_cond_wait@@GLIBC_2.3.2 () at 
../nptl/sysdeps/unix/sysv/linux/i386/i686/../i486/pthread_cond_wait.S:122
#2  0xb76639dd in __pthread_cond_wait (cond=0x80de870, mutex=0x80de858) at 
forward.c:139
#3  0xb771d14f in ?? () from 
/opt/GNUstep-trunk/Local/Library/Libraries/libobjc.so.4
#4  0xb742396e in start_thread (arg=0xb5db6b70) at pthread_create.c:300
#5  0xb7656a4e in clone () at ../sysdeps/unix/sysv/linux/i386/clone.S:130

Once I saw my main thread blocked on the same condition/mutex (I think
it was load_lock in NSBundle) : deadlock.

I'm wondering if my code is responsible by doing too much work in
+initialize methods (ie creating singleton).

Can someone explain where does this thread come from ?

Thanks,
Philippe
