Trial allows you to return a Deferred, which in you case is something
you would call after your endpoints close their connections. You can
grep through twisted sources though to see how this can be done
without network connections in unit tests - look for test cases using
the module simio.

You can close connections and reconnect etc. without "restarting" the
reactor - so I don't see how this is an obstacle.

This isn't really documented. But again, unit tests for twisted itself
provide good examples.
