https://jira.springsource.org/browse/INT-3004
Previously, reply messages were silently ignored if the request thread
times out or caught an exception, or had already handled a reply.
Add a WARN log if the client times out or catches an exception,
or has already received a reply.
Optionally make these fatal; at this time, we are not exposing
this boolean on the namespaces see INT-3005.
