Some folks came up with a cool hack in 0.8 that makes acks=0 send no
response. This changes the performance for small message sends to be
equivalent to 0.7. This is proposed for inclusion in 0.8. It would
obviously be less useful for the java/scala client in 0.9 if we are able to
properly pipeline requests, but it would still be a valid option for
non-java clients who don't want to deal with the complexity of request
pipelining. JIRA is here for discussion:
