No, it's a different issue.  There are problems in VMware.  I got a note
from a certain large commercial company which uses cwsdstub in one of
their products - which was forwarded from the VMware developers asking
for help.  It seems that the commercial APP + CWSDPMI is a nice torture
test for emulators due to all the mode switching, etc.

The last time I had email correspondence I was going to review the 
alignment on the GDT (and other structures) and number of times those
structures were modified.  CWSDPMI always sets some bits (even if they
are already set) and this significantly slows down the emulator (to
the point it may not be able to keep up with what needs to be done).

I haven't done anything on it (yet).
