Comment(by robertwb):

 Either we make this variable a global (ugly) or return it on from call to
 doc_preparse along with the parsed docstring (also ugly). All to save a
 fraction of a block (~1KB) of an ephemeral file and < 1ms on an already
 fairly expensive operation. If we're looking to cut fat, it'd be better to
 avoid the quadratic-time creation of the doctest file string.

 The name clash is a red herring--if we avoid it only because # tol is not
 used, that's a potentially latent bug in my mind. The function could be
 renamed if need be.
