closured function fails with RecursionError

[mmckerns]

Originally reported by @jetheron in #129.

import dill

def foo():
    def _foo():
        if not hasattr(_foo, '_counter'):
            _foo._counter = 0
        _foo._counter += 1
        return _foo._counter
    return _foo

f = foo()
f()
f()
dill.dumps(f)

@matsjoyce: I think this is one issue we run into all the time, and here's a solution:

Hi, do we have an anticipated date for next dill release? Thanks!

Hi @tvalentyn. Yes -- but for a number of reasons (that I won't go into here) it's about 4 months late. However (and especially now that #469 is closed) it is literally the next thing I'm planning to do... and hopefully that means it will be out by this afternoon.
