just this: in your example, if parent needs to write more than some

larger than this limit and blocks on the write, it would be a problem.
i attached my example of using only one pipe which requires two
rendezvous points and customization of the slave proc; this could
have a deadlock when a child requires multiple reads to cause a write.
