No worries.  The background here is that the flapping tests have
started to really, really bug our team, so we have been wanting to
attack them so more of our internal builds pass, or at least fail on
the code we are changing!

We are aware of the irony of adding back one in dbcheck, but I'm
already chasing down the root cause there for a client, so that will be
fixed soon. 

Other other angle is that Garming is working with Robert O'Callahan,
the upstream for Mozilla RR, to get RR working on Samba so we can
understand the cause of the 'whole test run needed to reproduce'
flapping tests.  Indeed, we had a fun afternoon in a race to see if RR
or manual log inspection could get to the cause first! :-)
