+\item Evan Jones's patch to obmalloc, first described in a talk
+at PyCon DC 2005, was applied.  Python 2.4 allocated small objects in
+256K-sized arenas, but never freed arenas.  With this patch, Python
+will free arenas when they're empty.  The net effect is that on some
+platforms, when you allocate many objects, Python's memory usage may
+actually drop when you delete them, and the memory may be returned to
+the operating system.  (Implemented by Evan Jones, and reworked by Tim
+Peters.)
