It isn't hugely important, but with sys._getframe() unlikely to appear
during runtime, the following may make more sense:

if hasattr(sys, '_getframe'):
    def currentframe():
        return sys._getframe(1)
else:
    def currentframe():
        pass
currentframe.__doc__ = "Return the frame of the caller or None if this
is not possible."

(Oh, and there's a typo in the docstring...)

Cheers,
Nick.
