+# The following example may crash or not depending on the platform.
+# E.g. on 32-bit Intel Linux in a "standard" configuration it seems to
+# crash on Python 2.5 (but not 2.4 nor 2.3).  On Windows the import
+# eventually fails to find the module, possibly because we run out of
+# file handles.
+
+# The point of this example is to show that sys.setrecursionlimit() is a
+# hack, and not a robust solution.  This example simply exercices a path
+# where it takes many C-level recursions, consuming a lot of stack
+# space, for each Python-level recursion.  So 1000 times this amount of
+# stack space may be too much for standard platforms already.
