I fully agree. I have just the impression that Mr 4of10 doesn't need
2 programs running in 1 VM. Starting TEST1.EXE and TEST2.EXE in 2 more
VMs could fit (could Mr 4of10 confirm ?).
That you can easily with DR-DOS (there is an equivalent to Win9x's
Start "DOS" command).

It is not free-"libre" (free speech) but is free-"gratuit" (free beer)

For certain things, free-"gratuit" is a good thing (not the best) IMHO...
Back to multitasking, I'm not sure that the intra-VM multitasking API of DR-DOS
isn't compatible with DPMI programs - read

(I don't have a certain answer but there are mentions of "DPMI")
