If/when you upgrade to 2.6.x you'll notice that even on the vast
majority of abnormal reboots, it still won't reconstruct. The code in
2.6.x marks the array as "clean" very quickly after writes stop so
unless the array is actually being written when it goes down, its
probably okay. On a huge array, that's nearly worth the upgrade right
there...
