Comment:

 Looks good.

 Very similar to the QueryCleaner we recently added :) Is there a known
 pattern name for this? (I.E. RAII-style resetting of reusable objects,
 RAII itself doesn't seem to apply).

 Perhaps we should make a naming convention for it;
 holder/cleaner/whatever. Would be a bit of a bikeshed discussion in itself
 but it would be nice to be able to immediately see the purpose of such a
 class when it is used.

 Anyway, it can be merged if not :)
