This makes a lot of sense - that is the only HW interrupt which is hooked
by default by DJGPP images (to catch ^C).

It's something strange in your environment.  I suspect the Norton Cache/Himem
setup, since mode swaps/memory access is less controlled than under EMM386.
The Norton Cache may also be a real mode stack hog, or do something naughty.

I would try first running EMM386 to see if the presence of VCPI makes it 
better behaved.  You could try to increase the CWSDPMI heap size, but I
doubt that would help much.  Try another disk cache.
