NT named pipes don't have the right semantics to be used to implement
UNIX named pipes. As far as I was able to figure out, they would need
to be implemented from scratch based on shared memory areas.

At one time, I started to work on an implementation of this. I
couldn't get any advice regarding cygwin internals (you know what
happens if you email Chris directly) and I couldn't post to the
mailing list because of the damn ORBS filter, so I eventually bagged
it. Have since chucked NT as well and work on Linux full time. Much
happier. Emulate Windows when necessary, instead of the other way
around.
