It's possible (and perfectly logical, at least to me) to implement the
pty case on the server side by allocating one pty to use for stdin and
stdout, and a separate pipe for stderr. But when I tried thet, some
shells, notably bash, seemed to get into problems.

Anyway, I don't see a big problem with having the same flow control
window for stdout and stderr. Not sure what to think about the multiple
fd case, since it's unclear to me what the applications are.
