+* ``sys.setrecursionlimit()`` is ignored (and not needed) on
+  PyPy.  On CPython it would set the maximum number of nested
+  calls that can occur before a RuntimeError is raised; on PyPy
+  overflowing the stack also causes RuntimeErrors, but the limit
+  is checked at a lower level.  (The limit is currenty hard-coded

+  Linux.)
