There are less environment variables, because more things are
determined at link time or automatically.  signals and critical errors
should be easier because it's pure DPMI so you don't have to worry
about what go32 will (or will not) support.

DISPLAY.EXE does all this and is pretty cool.  It relies on good
documentation for setup.
