Yes I noticed that in the xterm man page, but does the app then have to
deal with the pty interface?  I remember wanting to use that for
something once, and it looked kind of messy in the docs, and I ended up
not pursuing it.  I guess if the xterm can just inherit a file
descriptor and not have to mess with pty devices, that can be simpler
than the named pipe approach.
