They do, it's true -- these are rrds holding data from cricket.  That said,
when I do dump and restores, the data that cricket displays are the data
from the most recent restore.  If I've just restored the dump from the old
rrd, cricket displays the old data only, and then a two week gap.  If I've
just restored the dump from the newer rrd, cricket only displays the most
recent two weeks.

So clearly there's some merging trouble, though whether it's a problem with
cricket or a problem in the rrd itself, I'm not sure.
