[Stackless] Why would a channel stop listening?

My apologies, I found a function trapped in an infinite loop (that old 
chestnut). I guess my lack of experience with stackless channels caused 
me to look in the wrong place.

stackless may be concurrent but its not multithreaded, so a function 
which doesn't return is bad news for all the other tasklets eh?
