? I thought you wanted a timer routine; can't you use the the winmm timer
services as mentioned? They don't require the message loop.

Well, not to be flippant but one solution is to use a message pump.
Frankly, that's the 'right way' to do it. I realize this would be a
radical redesign in many ways. The other thing to do is use the threads
that NT provides, which are much lower weight than Unix threads.

Depends on how much real time you need; it's real time enough to play
musical instruments and record music. NT is also real time enough to burn
CD's and other things, but to get this level of timers you have to mess
with vxd's, which I think is overkill for Kaffe, but I could be wrong.
