the status of this series was one of the topics of yesterday's
community call. Since Paul's prior ping hasn't had a response by
you (possibly because you're on PTO for an extended period of
time) the plan is to get this series in with as much of
reviewing that I was able to do by, perhaps, the middle of next
week. Unless of course we hear back from you earlier, giving at
least an indication of when you might be able to look at this.

Thanks for your understanding.

Paul, I notice v4 patches 10 and 11 never arrived in my inbox.
The list archives also don't have them. Therefore I can't check
the status of the tools side changes, and I don't think I'd
want to commit those anyway without tool stack side acks, the
more that they weren't part of what I've looked at.
