Take a look at the example I posted to the mailing list last Friday for 
an example of how I did this (per-yield chunk size, not delimiter 
based).  It greatly simplified my gzip/gunzip code.

Also, the "byte pipe" I'm using can surely be accelerated by using 
iovec (in sandbox/exarkun), I basically rewrote it and extended it so 
it could accomodate pipe usage.

If I end up finding any significant use for flow, which I almost 
definitely will, I'll help you out with that.
