I haven't done that yet since it's a different format than the one I used to
load up the RRD, but my understanding is that it's still kind of the same
problem that I have to stop updates, dump the file, fix it, restore it, and
restart updates, which will give me a hole.

I would really like to just feed the missing data samples in the RRD with 
a bunch of 
rrdtool update housepower_21.rrd 1242148828:500000853:500000071:500000070:499999218:499999999
commands to feed data samples in the middle of the file (since I'm giving
the time index) and not just at the end.

Is that not possible?
