+// Support for parallel and optionally concurrent state iteration.
+//
+// Parallel iteration is for the exclusive use of the GC.  Other iteration
+// clients must use serial iteration.
+//
+// Concurrent Iteration
+//
+// Iteration involves the _active_list, which contains all of the blocks owned
+// by a storage object.  This is a doubly-linked list, linked through
+// dedicated fields in the blocks.
+//
+// At most one concurrent ParState can exist at a time for a given storage
+// object.
+//
+// A concurrent ParState sets the associated storage's
+// _concurrent_iteration_active flag true when the state is constructed, and
+// sets it false when the state is destroyed.  These assignments are made with
+// _active_mutex locked.  Meanwhile, empty block deletion is not done while
+// _concurrent_iteration_active is true.  The flag check and the dependent
+// removal of a block from the _active_list is performed with _active_mutex
+// locked.  This prevents concurrent iteration and empty block deletion from
+// interfering with with each other.
+//
+// Both allocate() and delete_empty_blocks_concurrent() lock the
+// _allocate_mutex while performing their respective list manipulations,
+// preventing them from interfering with each other.
+//
+// When allocate() creates a new block, it is added to the front of the
+// _active_list.  Then _active_head is set to the new block.  When concurrent
+// iteration is started (by a parallel worker thread calling the state's
+// iterate() function), the current _active_head is used as the initial block
+// for the iteration, with iteration proceeding down the list headed by that
+// block.
+//
+// As a result, the list over which concurrent iteration operates is stable.
+// However, once the iteration is started, later allocations may add blocks to
+// the front of the list that won't be examined by the iteration.  And while
+// the list is stable, concurrent allocate() and release() operations may
+// change the set of allocated entries in a block at any time during the
+// iteration.
+//
+// As a result, a concurrent iteration handler must accept that some
+// allocations and releases that occur after the iteration started will not be
+// seen by the iteration.  Further, some may overlap examination by the
+// iteration.  To help with this, allocate() and release() have an invariant
+// that an entry's value must be NULL when it is not in use.
+//
+// An in-progress delete_empty_blocks_concurrent() operation can contend with
+// the start of a concurrent iteration over the _active_mutex.  Since both are
+// under GC control, that potential contention can be eliminated by never
+// scheduling both operations to run at the same time.
+//
+// ParState<concurrent, is_const>
+//   concurrent must be true if iteration is concurrent with the
+//   mutator, false if iteration is at a safepoint.

+//   object, false if the iteration may modify the storage object.
