We do!  The problem is a child cannot free the CS, SS, PSP and ENV selectors
it is using.  It's just a pure and simple MS bug with no effective workaround.
Don't do big builds under broken environments.  Even better yet, write MS
a letter, I'm sure they'll fix it in Win 98.

They are nested clients - but each is separate.  In a DPMI 1.0 world each
would have it's own IDT/LDT/pagetables.  Under DPMI 0.9 they share these
resources.
