>>> import sys
>>> def docstring():
...     return sys._getframe(1).f_code.co_consts[0]
...
>>> def foo():
...     print "My docstring is %r" % docstring()
...
>>> def bar():
...     "bar's docstring"
...     print "My docstring is %r" % docstring()
...
>>> foo()
My docstring is None
>>> bar()
My docstring is "bar's docstring"

No idea how brittle that might be, though.
