Re: 'PUT' transaction reconsidered (was Re: two-phase send concerns )

Probably should take this to the persist list, or the http-ng mailing list
(now at http-ng@cuckoo.hpl.hp.com)

The NG approach to HTTP/1.X encapsuation and persistent connections makes 
this tradeoff easier, since cancellation doesn't require the connection 
to be torn down.

The RTT costs with this approach using optimistic transmission are 0 RTT 
for the successful case, and approximately 1 in the event of failure (the 
costs can be greater than one if data is being  enqueued at the TCP layer 
faster than the TCP transmission rate; the excess data is then drained.
