I noticed that a couple of people tested DPMI for the combination
Windoze & QEMM.  Note that (according to the docs with QDPMI) QDPMI
will step into the background when it sees Windoze's DPMI server start
up.

(Any DPMI server---except of course Windoze---will presumably defer to
a preexisting host.  What QDPMI's docs say is that it will defer to
Windoze if Windoze starts up *after* QDPMI.)  Unless they plan to
change this in future releases, this may mean that you can't get DPMI
ver. >0.9 until MicroSoft supports it.
    Is this a correct analysis?  I don't know how to test it.
    I apologize for raining on the parade of all the Windows
developers who like DJGPP.
    Does anyone know what 386MAX does in this situation?
