>Description:
sigprocmask() fails to block signals in threaded applications

>How-To-Repeat:
I have setup a page <http://schurli.wu-wien.ac.at/threads/> where
you can try signal.c and signal_t.c (use the supplied Makefile!)

>Fix:

Fix requires some hacking and discussion, I assume. I would like
to participate in the discussion, if possible! - Thanks!

  yours,
    George
