Some apps need very fast context
switching of a massive number of logical threads of
control, such as games, telco, and web servers,
where pre-emption is out of the question because it
is much too slow and resource hungry.

EG: telco system, 600 calls/second [the rating of
a commercial analogue switch], 3 min average call --
you need 100K threads. 

I can run 500K Felix threads on my 700MHz PIII
using a coroutine like facility: when you need coroutines, 
pre-emptive threads just won't suffice (on a Unix box)
