+ * THIS IMPLEMENTATION FOR THIS INTERFACE IS INCOMPLETE.
+ * NONE OF THIS HAS BEEN TESTED.  DO NOT USE.
+ *
+ * Comments on the interface are appreciated, especially from
+ * potential users of the interface.
+ *
+ * This is a Bartlett style copying collector for young objects.
+ * We assume for now that all objects allocated through this
+ * mechanism have pointers only in the first BITMAP_BITS words.
+ * (On a 32-bit machine, BITMAP_BITS is 30.)
+ * Objects allocated in this manner should be rarely referenced
+ * by objects not allocated either through this interface, or through
+ * the typed allocation interface.
+ * If this interface is used, we assume that type information provided
+ * through either this or the typed allocation interface is valid
+ * in a stronger sense:
+ *
+ * 1) No pointers are stored in fields not marked as such.
+ *    (Otherwise it is only necessary that objects referenced by
+ *    fields marked as nonpointers are also reachable via another
+ *    path.)
+ * 2) Values stored in pointer fields are either not addresses in
+ *    the heap, or they really are pointers.  In the latter case, it
+ *    is acceptable to move the object they refer to, and to update
+ *    the pointer.
+ *
