wondering if this is really useful.

If we do renderDrafts in the same time and this is not finished, we'll end up doing twice the same request, which is probably not a good thing.

So 2 possibilities:
* either we do something smarter in Drafts.request: if a request is ongoing, just store the handler, and run it when the ongoing request is finished
* or we remove this line now and we file a bug about doing this properly later
