Hitting recursive depth causing all notebook pages to hang

[mrmagooey]

The following will cause all IPython 0.13.1 notebook pages to become unresponsive:

class Blah(object):
     def recursive_function(self):
         return self.recursive_function()
b = Blah()
b.recursive_function()

This will cause all notebook pages open in the browser to become unresponsive and need to be killed (tested current Chrome and Firefox). Firefox will report that something in utils.js has become unresponsive. Just to be clear, this would otherwise be expected to raise RuntimeError: maximum recursion depth exceeded.

The error is being raised - the issue is simply rendering the massive traceback in javascript. I expect it's the regular-expression operation that turns ANSI colors into css that's the culprit. It's possible that is not written in an appropriately efficient way, and we should probably also have some truncation of tracebacks to protect against this sort of thing.
