Jamie & Bryan,

Thanks for your input on the user-to-user copy problem.  I won't pretend 
to understand all the issues of which you speak.

Are these issues insurmountable?  Is it worth it?  Would the extra 
complexity of the user-user copy add security holes and stability problems?

If someone were willing to work on copy_user_to_other_user, I could 
manage the pipe work.
Anyone feel like battling that windmill?
Eliminating one out of two buffer copies is a fine and noble goal.  
Something you can brag to your grandkids about ;)

BTW, it seems this could make unix sockets faster too.
