How hard is the caller blocked?  If it can't receive any messages then
how would a normal program, the venerable "sleep" program under Unix for
example, receive any other messages, say the equivalent of a SIGTERM
under Unix.  Or am I missing something and interruption of sleep is
unnecessary/bad in some way.  The only way I can see it working is with
a helper thread, but then I seem to get into all the reasons for why the
IPC mechanism was changed for Coyotos.
