#255: Nested parallelism
--------------------+-------------------------------------------------------

--------------------+-------------------------------------------------------
 The existing parallelism infrastructure needs to be re-factored so that
 rather than a single global state, a stack of parallelism states can be
 constructed.  To bootstrap our way into this, avoiding the problem of
 setting up and destroying nested communicators in a general fashion, we
 should be able to turn off parallelism after creating an iterator.  i.e.,
 this would enable iteration over multiple of an object in a user script,
 and then a return at the end to a collective operation.
