Stopping right here (being lazy):
     <from sun's manpage on pthread_sigmask>
     If sigprocmask(2) is used in a  multi-threaded  program,  it
     will be the same as if thr_sigsetmask() or pthread_sigmask()
     has been called.  POSIX leaves the semantics of the call  to
     sigprocmask(2)  unspecified  in a multi-threaded process, so
     programs that care about POSIX portability should not depend
     on this semantic.

So try pthread_sigmask instead.
