Arbitrarily, it seems, I am getting this message:

Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib/python2.6/threading.py", line 525, in __bootstrap_inner
    self.run()
  File "./fbfriendsgraph.py", line 149, in run
    iconnections = self.fb.friends.areFriends(ilist, myfriends)
  File "<string>", line 6, in areFriends
  File "/home/nathaniel/Desktop/fbfriendsgraph/facebook/__init__.py", line 517, in __call__
    return self._client('%s.%s' % (self._name, method), args)

    return self._parse_response(response, method)

  File "/home/nathaniel/Desktop/fbfriendsgraph/facebook/__init__.py", line 890, in _check_error
    raise FacebookError(response['error_code'], response['error_msg'], response['request_args'])
FacebookError: Error 4: Application request limit reached

This has happened for me at 29%, 31% and 61%. My friends tree has not changed, and assuming that the programme walks a tree in a deterministic way, it seems like facebook is being somewhat arbitrary.
