That's about right.

Yes, in 1.11 it correctly detects that out-of-memory condition.  At
least, it's supposed to.

PTs are dynamic - they depend on the size of your executable, and
conventional memory is used for regular paging as well.

2.0 under Windows uses about 10K per program instance.  This is about
5K for the stub loader, plus 3K for the Windows DPMI buffer, plus
however big your environment is.  Under QDPMI, it's about 100K due to
the DPMI buffer.  There is no go32 in 2.0, but it does require loading
a DPMI host.
