Well, this would be possible under a multi-tasking DPMI host, but
neither CWSDPMI or the DPMI emulation under win32 provide this kind of
functionality.

AFAIK, there are no free multi-tasking DPMI servers available, in fact
the only one I can think of at all is OS/2, but thats more than just a
DPMI server. :)

Unfortunately, DPMI arrived too late on the scene, and DOS was rapidly
eclipsed by Windows, so developments in that area have been stagnant
for a long, long time. (with the exception of CWSDPMI of course)

There is of course nothing preventing you from writing a multi-tasking
DPMI server, but that's going to be a big job.

Good luck.
