It's been a nice simplification in my work, but I haven't used it with
anything where success > 0, or where I've even cared about results other
than failure.  And the advantage is that the incremental effort of
batching a series of calls is very small.

I just thought it might be useful.  Perhaps the interface could be
extended to be more useful in the cases you're looking at.
