I seem to remember IBM tried this for v2.0(?) and found that there was too
much of a performance penalty in the conversion (or
"re-routing").

I also remember more recently a discussion on Usenet about whether or not
IBM was going to implement the Win32 API directly in this manner or not for
future versions of OS/2.  Apparently, there is much less of a performance
drop when "re-routing" the Win32 API - probably due to both using
a flat memory model (Does the Win32 API use a flat memory model?  I don't
know *anything* about the Win32 API and very little about the Win16 API).

bcnu,

Richard.
