Digital Research (makers of GEM) make a product called CONCURRENT DOS
which is full blown multitasking for DOS.  It is unrelated to the GEM
product line.  However, you can have one of the tasks under CONCURRENT
DOS be a Graphics program, such as a GEM program (note, only ONE).
GEM only allows one process to be resident, open, whatever, execpt for
a print spooler which can run in the background.

CONCURRENT DOS is now available for the '386 and is supposed to be really
nice.
