Yes, for a long time it solved the problems. But with the growth of
users of the application, I couldn't find any solution with nice,
mostly because everybody is "fighting" for the CPU in the same nice.

I also tried using different nices considering the usage profile of
each users. But it didn't work also, because the users doesn't behave
the same way all the time.

This works because GIMPS is with a high nice, and everything else is
not. You have two different application profiles, so nice fits
well. In my case dosemu is the most important application on this
machine.
