[Stackless] tasklet sleep()

[Andrew Tutt]

As I've noted elsewhere, all sleep() functions in stackless are inherently
busy sleep because they are being continuously rerouted to the scheduler.
You can reduce the business by putting all the sleeping tasklets into a
single continuously scheduled function, but you cannot eliminate the fact
that at least one function is going to be constantly scheduled and
rescheduled to check that there are no tasklets to wake at any given time.

This is because all the program execution happens on one thread. It's not
necessarily a terrible thing, but it is an interesting fact. That's why I
like to call it a "wait()" function as opposed to sleep, since the CPU is
still jamming when you're supposed to be "sleeping"
