It works fairly well, but not too well. DOSEMU doesn't address this problem besides from the suspending whenever the dosemu window is iconified. My idea was *not* to schedule a process for running, even if it is the only runnable one, if it is marked as a "presumably bad mannered" process and consumed its previous timeslice to the whole. Instead an idle slice is done. After a configureable amount of time, the bad mannered process is allowed to run again. I know it's a crude idea for everyday Linux processes, but for dosemu driven applications, which behave badly in a multitasking OS *and* for which source code isn't available, it may be worth to discuss.
