> The MutexTransport creates a massive bottleneck in a multi-threaded
> application that uses timeouts for sending messages. This scenario makes the
> assumption that the failover protocol is being used to automatically
> reconnect to a broker that goes offline. If multiple threads are sending
> messages that have a send timeout and the broker is currently offline, then
> those calls get queued up in serial instead of executing in parallel. For
> example, if the send timeout is set to 10 seconds and 50 threads are
> simultaneously sending a message, it will take 500 seconds for all fifty
> threads to finally error out. The programmer of the code would expect the
> timeout to be 10 seconds maximum in order to have acceptable application
> performance.
> The MutexTransport needs to honor and use the timeout value of the transport
> that it is protecting and allow parallel waits.
