Life is fun. 5 minutes later I discovered a bug that made blocking multiline
reads (with or without pattern) hang at the end of the first line. I sent sort
of a patch to cygwin list, but I am not sure if it really does the right thing
(it fixed the bug I've seen, O.K. The question is whether it introduced
another bugs :-)

Anyway, fiddling with currently released versions of cygwin is pretty useless
wrt to zpty (all of them are buggy in some way). Unfortunately (to us) zsh
seems to be the only program that has these problems. With all implications.

The pgrp problem still remains.
