[ale] md0 tasks taking 60-80% of CPU

[Jeffrey B. Layton]

That's what I suspected. Even my piddly little 40 GB takes a while.
I'm not sure why it has taken so long for 160 GB though. While
I haven't done it, there are ways to devote more CPU to the resync
process to speed it up. This may or may not be useful to you.

Enjoy!
