no. "approximately" in this case would mean "wrong".

for the time being, as i'm limited on time, i'm using pycsp
with a very slim wrapper around it to make its interface
palatable. it'll all be hideously inefficient, but i'm not
too concerned about that currently. i've attached it in case
anyone's interested.

joel: multiple readers and writers isn't the same thing as alt
at all - you need to be able to read from more than
one channel at once. sharing a single channel between
several processes doesn't get you that (although it's
great to have, and the plan9/inferno channel model
supports it)
