This seems to be a recurring complaint in this thread - has any
consideration been given to using werkzeug directly (its the library
underneath Flask). IMO this isn't a big win because the extra stuff that
comes in with Flask shouldn't present additional problems for us, but if
that really is the sticking point then it might be worth a look.

++. If there are issues we hit in Flask because of the extra components
we are so worried about then maybe we could work with them to resolve
these issues? I get the impression we are throwing out the baby with the
bathwater avoiding it altogether due to this fear.
