S'ok. I forgot it was there. I still think we should change
to display decimal, and introduce
to display in hex.

Nope. This deserves a chapter in the cookbook.
in occam actually causes a reschedule. If you have multiple parallel processes:
and you have a delay() call in proc.a, then proc.b and proc.c will
have a chance to execute while proc.a is sleeping. Likewise, when you
do a channel communication, that triggers an opportunity for everyone
else to have a turn.
So, in that regard, delaying is exactly *unlike* a delay in C++. In
occam, it is parallel-friendly out-of-the-box.
Does that make sense?
