I'm still trying to solve this problem, I've been testing some different
usleep times in different int calls, and the best I could achieve was
75% of CPU usage when idle, 1% when busy, with a very slow
responsiveness, but usable, up to 3 users.

Vanilla dosemu eats 98% CPU, 1-2% when idle, and has an excellent
responsiveness when there is only 1 user. And its still usable with 2
users, if there is a third it becomes unresponsive.

It's pretty annoying that when the application is doing something it
drops the cpu usage.

In my case, it's not about money. I have to fix this so my users don't
kill me. But you are encouraged to donate money to the dosemu project.
