I am reminded of Spaceball's 'ludicrous speed' here. This is after a
reboot from 2.6.16-rc1-mm3 (where the array was built) to 2.6.16-rc1-mm5
(where rebuilding continued thanks to the bitmap).

Might I also add this bitmap idea is a GREAT thing to have!

I will dedicate myself to the study of dangerous assumptions.
There is power in them, which the Nahia have neglected.
