Maybe I'm making things harder than necessary.  I want to issue an unsupported
int 21 call, and I thought I needed to load a real-mode program and have it
make the call.  Can I, instead, set up data areas in real memory, then get the
real-mode int 21 vector and do a _go32_dpmi_simulate_fcall_iret() to that?
