Hmm.  You don't say what OS you're using.  If you're using Linux, could
you try doing a system-call trace on the multiplexor:

	strace -p process-id-of-multiplexor > TRACE.OUT 2>&1 &

On Solaris, the command is "truss" and on BSD, I think it's ktrace
(but ktrace does not directly produce human-readable output.)

It sounds to me like the multiplexor is blocking in a system call when
it shouldn't be, and I need to isolate where it's getting stuck.
