In the course of tracking down another issue I noticed that the c_writewaiter
field of the Connection structure is not getting cleared in connection_init(). 
This was causing me to get the "deferring operation" message under certain
circumstances.  Clearing this member caused the message to go away.  Sorry I
cannot produce a better bug report, but this was not my central problem and the
exact details of configuration, etc have changed and would require some effort
to reproduce.
