That of course is a completely different issue, and I agree this one
needs solving. But it's not clear at all that we need to change the
generic functionality that works just fine in other cases. IMO we
should change the way the async I/O works to avoid wasting file
descriptors. This probably means some kind of reference counting, but
since this is only necessary for async I/O it should be done there,
not in the generic code.
