I was going to use this myself in a program I am writing, but when I used 
the _dpmi_get_capabilities (or whatever) function, the bit which was 
supposed to represent page mapping ability wasn't set. (I used the 
get_capabilities function in case the program was being run under a DPMI 
0.9 host)

Is this a CWSDPMI bug? I didn't try the actual function because CWSDPMI 
said it couldn't do it -- maybe I shouldn't let the computer tell me what 
to do ;-)
