Actually, you won't see garbage.  There's a low probability that you'll see
the wrong docstring because the mismatch was not detected, and a high
probability that the mismatch will be detected and then the docstring
pointers are recomputed and things work correctly from then on.

The low probability is of the order "1/number of bytes in a docstring", so
less than 1%.
