[Clusterusers] now something seems really strange on fly

[Kyle Harrington]

I didn't have time to work on divisionblocks this weekend (or during
last week much either). So, I don't think this would have been caused by
the networking code. Also, I have only been running it for a few minutes
at a time, just enough to test out block transfer.
