Re-challenge is automatic whenever a new request needs to be authed and
the currently known credentials are unknown or too old to be used.

garbage collection only removes things known to be dead already. The
garbage interval determines how often the memory caches are cleaned out
above and beyond the regular as-used cleanings.

  nonce_max_duration determines how long the nonces may be used for.
It's closer to what you are wanting, but I'm not sure of there are any
nasty side effects of setting it too low.

Yes.
