With some memory managers, NOEMS implies NOVCPI; with others it does
not.  I didn't want to bother users with too many version-specific
information, so I simplified that.

If you say NOEMS, but not NOVCPI, the memory manager will still
allocate at least a frame page.  Some versions will even leave EMS
active, just not available.

In any case, VCPI is so tightly coupled with EMS that it is almost
impossible to have one but not the other.
