Mostly trying to standardize the way tests sleep for arbitrary amounts
of time to make it easier to tell at which particular point the
unit test actually may need the timeout interval increased (or else
debugged further).
Sometimes manager node was shutting everything down before others had
a chance to generate output. It now waits for all nodes to fully
connect with each other.
