Cleanup does perform transport lookups. Is redis performing well?

Well, since cleanup is slow, move the verbose logging to cleanup if
you can't determine why cleanup is blocked more directly.
Cleanup performs transport lookups, canonical and virtual rewriting,
header/body checks, writes and syncs the message to disk, and
sends a 1-byte notice to the queue manager socket. With inflow_delay
it also waits that long to receive a token from the queue manager.
One of these things is slow.
