This one probably breaks a whole heap of older Win3.x apps.
When I started the Win98 setup.exe for fun, it choked on int 0x21
"list of lists" (DOS_LOLSeg not initialized).
Trouble is that we initialize DOS variables in case of DOS programs *only*.
This is rather fatal IMHO, especially in the case of List Of Lists, which
is a pretty important structure with lots of information that some Win 3.x
programs might rely on.
Thus DOS stuff should be reorganized somehow.

Any suggestions ?

IMHO probably winedos should get loaded as soon as DOS3Call() gets called even
