This might be totally wrong, but from my reading of the exit code, it sure
tries. It looks like it writes some 16-bit code to its transfer buffer whose
job is to free the last selectors and memory block. Since this runs in real
mode, it shouldn't need any selectors of its own. Am I missing something?

Do I understand correctly that, barring a bug in the DPMI server, selectors
and such will be freed when the *parent* exits?
