XXX: think this is what ``preserve_context_over_deferred`` is supposed to do,

though it is broken, in that it only restores the logcontext for the duration

of the callbacks, which doesn't comply with the logcontext rules.

You can also use ``logcontext.make_deferred_yieldable``, which just does the
