That's one of my favorite hypotheses as well.

I'm sorry to say that I spent several hours pouring over the source
for the cygwin package and couldn't find enlightenment.  I just don't
understand much of the Cygwin architecture.  If someone can steer me
in the right direction or give me something to focus on, I will
happily dive back into the code.

That never occured to me as the IPC involved would seem to be of a
strictly Windows flavor.  None the less, it's an intriguing idea and
I'll give it a shot.
