On further consideration (and after some more profiling), I would
actually prefer inlining the speedup code directly into
OFS.Traversable.Traversable, to remove the extra function call as well
as to avoid the gnarliness of monkey-patching Python.  An alternative
would be to call 'quote' only once (for the completed string), rather
than repeatedly (for each path element).

The SF traffic for the bug is interesing:  the fix checked in is an
improvement, but not nearly as big a win for the case (very common in
English-language Zope sites, anyway) where the path elements are already
URL safe.
