   1 # The following example may crash or not depending on the platform.
   2 # E.g. on 32-bit Intel Linux in a "standard" configuration it seems to
   3 # crash on Python 2.5 (but not 2.4 nor 2.3).  On Windows the import
   4 # eventually fails to find the module, possibly because we run out of
   5 # file handles.

   7 # The point of this example is to show that sys.setrecursionlimit() is a
   8 # hack, and not a robust solution.  This example simply exercises a path
   9 # where it takes many C-level recursions, consuming a lot of stack
  10 # space, for each Python-level recursion.  So 1000 times this amount of
  11 # stack space may be too much for standard platforms already.
