Connection re-use does not prevent concurrency, you'd need a pool
of connections or parallel submission processes pulling messages
from the application queue. Concurrency is more important than
connection re-use. Connection setup is generally cheap, unless
your IP to name lookups are broken and slow for internal IPs.
