Wait, what? Huh? Well perhaps patch 25 makes a bit more sense now - at
least with respect to the usage of +=.... But I'm now beginning to
wonder if I've understood processing correctly.
I'm not quite understanding this whole sum of all the holes thing. I
thought much earlier patches were generating message queues for each
packet to be queued/dequeued and processed...

Uses older style... Will also be affected by a flags argument

Now we have an int being assigned the sum of a bunch of ULL's?

length could have been passed as NULL - I thought we avoided that back
in virStreamHoleSize by:
+ virCheckNonNullArgReturn(length, -1);
yeah - I know better safe than sorry; however, if !length then should
this function succeed?
