Remember, SVR3.2.2 doesn't have select.  The compatibility
version in XWIN only works with Streams files, since it's really
a Streams poll.  Until SVR4, which surely will have select, 
you could start a demon to read each pipe (blocking) and 
write to a pseudo-tty (streams, right?). Then read the ptty
in your X app.

I can't say for sure that this will work, so I'd be interested 
to hear back by email. ... rb
