Re: [Q] mp:schedule-timer-relative in LWW4.2

Thanks Dave (and Nick).  Specifying the output stream was what I was
missing.

The thing that threw me off was that I first tried scheduling the
timer with MP:SCHEDULE-TIMER and it executed the PRINC right away and
sent that output, correctly, to the Output buffer; but knowing what I
know now, that was probably because the absolute time I had,
incorrectly, passed it was already well behind the current run-time,
and the timer probably never got spawned in a new thread, with the
standard output redirected.

Anyway, thanks again.
