> Crate a new test exe that runs for a (configurable, default short) period of
> time, with a single proactor acted on by multiple proactor and user threads. 
> Run
> with helgrind or tsan to detect races.
> Exercise potentially racy APIs concurrently:
> - making, accepting and closing (from both ends) a connection.
> - pn_connection_wake
> - pn_proactor_release_connection
> - re-use of released pn_connection_t on a new connection
> - timeout
> - concurrent with some normal use: sending/receiving messages.
