Is anyone else using the spawno software and DJGPP?

For those not familiar with it, spawno is a set of functions which
will handle swapping to XMS, disk etc when one program spawns another.
It leaves only a few hundred bytes of the parent program in memory.

Spawno has performed faultlessly for me for quite some time, but ever
since I have been using DJGPP I now find a problem. I use spawno
in my DOS shell program (compiled with Turbo C, not DJGPP).  Most
of the time everthing works fine, but if the spawned DJGPP-compiled
program runs out of memory and starts swapping to disk then the parent
(my DOS shell) fails to operate correctly when it resumes. It appears
that the PSP of the parent is probably being corrupted.

If you use spawno, do you have similar problems?
