> Second, a question: is there any way to turn off go32's virtual memory?

Yes, the easiest way is to set the env var GO32TMP to point to a non-existent
drive.

Memory is never freed if allocated by malloc - it just goes into it's pool 
for reuse.  Since virtual memory is a function of the DPMI provider, in 
V2 it depends on what DPMI you are using.  CWSDPMI behaves the same way
as GO32 does (even use the GO32TMP var for now...) so the above will work
in V2 also if you use CWSDPMI.
