Hmm, that's interesting.  It shouldn't be possible for PrivateRefCount
(the last value printed) to become negative.  Can you give a sequence
for reproducing this notice from a standing start?

The notice isn't especially worrisome in itself, but to the extent that
it implies some incorrect bookkeeping of buffer refcounts, there could
be a problem lurking somewhere.
