well, i don't know either but i think it was a good hint!
If i now set binary modes as early as possible on both sides
then things seem to work (i also had the problem that Matthew
got with "py.test -f" consistently and now it's gone,
and py.test py\execnet tests partially failed on my
installation and now they pass).
Could you maybe svn-checkout
http://codespeak.net/svn/py/release/0.9.x
and after a "setup.py install" report back if it helps?
cheers,
