Hi all,

This is subset 2 of the larger RDS-TCP patch series I posted last
Oct.  The greater series aims to correct multiple rds-tcp issues that
can cause dropped or out of sequence messages.  I've broken it down into
smaller sets to make reviews more manageable.

In this set, we correct a few RDS/TCP connection handling issues, and
message loss issues.

The entire set can be viewed in the rfc here:

Questions, comments, flames appreciated!
Thanks!
Allison
