>Description:
sigsuspend() bug

Thread aborts at /usr/src/lib/libpthread/thread/thr_sigsuspend.c line 77 with "oldsigmask is not cleared" when the main thread tries to pthread_cancel() it.

FreeBSD 4.x (libc_r) does not have this problem.

>How-To-Repeat:
      
>Fix:
The easy solution :-) remove:
THR_ASSERT(curthread->oldsigmask == NULL, "oldsigmask is not cleared");
