Well, it does illustrate the cost of spawning and 
the cost of message passing, and how the cost depends
on the number of concurrent processes.

It's been a while since I looked at Stackless Python,
but I believe its "processes" are not quite as 
capable as Erlang processes, esp. in terms of fault
tolerance and debug support. By all rights, they should
be cheaper than Erlang processes...
