I misunderstood my debugging output for schedinit() and thought it
was being called twice whereas both paths through it were exercised
before the machine stalled (remember north_'s fix?)
The problem is that the machine hangs after the second invocation
of sched() (port/proc.c). I have no idea how far it goes into the
second invocation, I think I could work my way throught the first
to get a better grip on what's going on.
I'll also follow up jmk's recommended reading, but probably not
right now :-)
