Neil - I see myself more as being an "idiot-proof" tester than a 
beta-tester...

One comment - As I look at the rebuild, which is now over 20%, the time 
till finish makes no sense. It did make sense when the first reshape 
started. I guess your estimating / averaging algorithm doesn't work for 
a restarted reshape. A minor cosmetic issue - see below
