How does the !proxy method of passing command lines from stub.exe
to go32.exe work?  Does it just pass a pointer to go32 that
points back into stub.exe's address space where the info is located?  If
so, then this could be a source of problems:  Shell Room would
swap that info out (well.. actually... go32.exe would over write
it when it's loaded... but same net effect).  

I suppose this would also affect my suggestion of using one of
the swaplib functions used in the dos-only port of gnu make a few
years back.
