When you embed a Swarm in a Swarm or two Schedules in a Swarm, the
simulator is incrementally merging the Actions from all the model
components into a single linear sequence.  The larger a simulation
gets, the more dense this linear sequence tends to get, and often many
time steps will have multiple actions on them.  When this happens
there are physical lists of concurrent Actions inside Swarm, and these
lists, in principle, could be traversed in asynchronous way.  Like if
you have five friends and you go tell them to do something and come
back to you when you're done.  It's more complicated than that, but
that's the basic idea.  This is not currently implemented in Swarm.
