Charles, let me see if I understand what you are proposing.
Do you suggest to make the I/O hooks in a child use a PM interrupt,
and for the parent to install a PM handler for that interrupt?
Or do you suggest to pass CS:EIP between the parent and the child and
use those to ljmp between them?
If you meant the interrupt way, then which interrupt would you suggest
to use? Is the DPMI interrupt 31h a good candidate?
Also, there's a question asked by Salvador about notifying the DPMI
host that the client has been switched. I presume that the host needs
to know that, to correctly handle the client's requests. But I don't
know whether there's a way to do that, even for CWSDPMI.
