Comment:

 Okay, it looks like this is happening while we get a write event on a
 connection in state OR_CONN_STATE_TLS_SERVER_RENEGOTIATING.  We then call
 "connection_or_handle_read", since we expect that we're in read-blocked-
 on-write state.  But in fact there is nothing to read.

 I have a more or less totally untested fix in my branch "bug5650" in my
 public repository. It's against 0.2.3.  It needs testing!

 I'll also attach it as a patch.  Please let me know if it stops this bug,
 or breaks the server entirely, or what.
