[uClibc-cvs] uClibc/libpthread/linuxthreads signals.c,1.4,1.5

[Erik Andersen]

Update of /var/cvs/uClibc/libpthread/linuxthreads
In directory nail:/tmp/cvs-serv21436/libpthread/linuxthreads

Modified Files:
	signals.c 
Log Message:
Alexandre Oliva writes:

A program that requests __pthread_sig_debug to be blocked will
self-deadlock when it requests a thread to be created, because the
debugger (rda or gdb) will never get the signal, so it won't wake up
the pthread manager as expected.

This patch fixes it.
