Hi all,

I just read http://wiki.squeak.org/squeak/5682 that Tim (I think it was) 
mentioned, and found the part about doing alternative scheduling with a 
higher priority thread interesting.

The question I had was, in the example it says the high priority process can 
use Delay's to sleep while other processes are running, but what happens 
when a process does IO?  Doesn't that cause the process to yield?

What I am thinking is, if I were to make a scheduler process that manages 
all running processes, how can he find out every situation where a process 
yields in some way?  It would be ideal if there was a Delay 
millisecondsOrUntilInterupt: type message.

Thanks,
Jason
