We use pipes in session.c to support the "half-closed for reading"
extension (see
http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/PROTOCOL?rev=1.12;content-type=text%2Fx-cvsweb-markup;ln=1#l34)
since socketpairs don't reliably provide the signalling that we need on
all OS's.

bash's behaviour has been incorrect pretty much all along; pipes vs.
socketpairs has been a per-platform decision in OpenSSH for some years.
IMO it would be better to fix bash.
