----------------------------------

I posted a WIP a while back here: http://gerrit.cloudera.org:8080/#/c/1494/
but it's not happening often anymore, so bumped to backlog.

> Currently, the server is responsible for timing out RPC keepalive connections. This means that there can be a race where a client sends an RPC exactly at the same time that the server is about to close the connection due to keepalive. In this case, the client gets a "Connection reset by peer" trying to read its response, and the RPC fails.
> I've seen this cause a failure of linked_list-test once.
