A clarification - the windows WaitForMultipleObjects call you refer to still 
has a limit of MAXIMUM_WAIT_OBJECTS handles : that number is, surprise 
surprise, 64.

Real high-performance i/o on windows requires io completion ports : my xp 
box runs out of buffers for o/lapped io at 3,976 open sockets  x 2 
(client+server apps).

The real design issue anyway is how to structure Lua apps around nonblocking 
io / events : how to schedule coroutines, associate them with events, add 
extension libraries etc.
