If the swap file goes completely full, CWSDPMI prints the message and exits 
(it doesn't expect this condition, already returned memory to the application 
based on the fact there was free disk when the request was made, but
something used the disk space in the meantime).  If it's nested, the
task causing the problem get's it's DPMI stuff cleaned up, but when it
returns it appears we didn't properly reenter the parent image (why?  I
don't know without a complete error log...)

I don't know how much if this is due to running out of disk/memory, old
CWSDPMI behavior and new CWSDPMI behavior.
