The basic problem here is a mixture of asynchronous mechanisms (futures, and
listeners) and then a listener making a synchronous `executeRemoteCommand` call.
The immediate cause for blocking is that internally a lock is held, which
prevents any more incoming messages for that session being handled until that
listener is done. "Fixing" this in a transparent and scalable way inside the
library looks very difficult.
A quick work-around for your case would be to make that listener use a
different thread for everything after `logger.info("Authed: $authed")`.
