IEEE Std 1003.1-2001 states that signals are posted to an
arbitrary thread in the process.  The sems code seems to
assume that the signal is posted to all threads.

This patch blocks all signals in all threads.  For a RTP
Scheduler thread to receive the RTP timer, it explicitly
unblocks the alarm signal.
