I think what the OP really meant to ask whether GIMP requires a *pre-emptively* multitasking OS. I.e. one that can interrupt a running process that has exceeded its timeslice, even if it doesn't do any system calls (or similar) that gives the kernel a chance to let another process have the CPU. (For instance, Windows 3.1 wasn't able to do that.) As far as I can guess, sure, GIMP might work on such a system... as long as it has other functionality that GIMP and GTK needs. That's the main problem, not having pre-emptive multitasking would to me indicate there's a good chance that the OS is very lacking in other respects, too. --tml
