Ok, false alarm (sort of, I'm still interested in what happens with odd device sizes), but it was a 
thinko in the raid6 parity block locator.

We have liftoff. It has now performed 2 raid5->raid6 and back again cycles.
I test it by using dd to dump 400mb of /dev/urandom to the device and then running md5sum on it, so 
far we have 4 complete cycles to differing devices in different orders and different sizes (As long 
as it stays above 400MB of course) and it's all good.
Hope to have something cleaned up and presentable in the near future.

Brad
