This is why you get the unoptimised version.  Had you selected
both as built-in or both as modules, then it would have worked
as intended.

If we're going to do this we should do it in the crypto layer,
and not litter every single crypto API user with such crap.

Currently we don't invoke request_module unless no implementation
is reigstered for an algorithm.  You can change this so that it
also invokes request_module if we have not yet done so at least
once for that algorithm.

Patches are welcome.
