Timeout after five seconds
Set a five second timeout to ensure we don't block endlessly if we send
a WebSocket message and don't receive a response in a reasonable amount
of time.
Chose five seconds arbitrarily, but that seems like more than enough
time to do our work. If it takes longer, something else is probably
wrong.
