Sorry, I've been trying to get a bunch done before the holiday break.
I'll try to see if I can look at this today. I'll be pushing out your
port of the rtmutex code today. Heh, I need to update it to your latest
changes :-)

Anyway, after today, I'm off till Jan 3rd, so anything not done today
will need to wait till then.
