As far as I know, Mario's quote from the docs is just plain wrong.  The
allocation of memory results in some kind of selector being mapped, and
that selector will have whatever length is appropriate for the allocation,
subject to 4 KB granularity.  That is, if 1 byte is allocated, then the
selector is mapped to a 4 KB area of memory.  You cannot then call
DosSetMem() to commit more memory than the allocated selector length under
any version of OS/2.
