I have a small patch to mdamd which allows the write-behind amount to be
set a array grow time (instead of currently only at grow or create
time). I have tested this fairly extensively on some arrays built out of
loop back devices, and once on a real live array. I haven't lot any data
and it seems to work OK, though it is possible I am missing something.

Sounds like a useful feature...

Did you test the bitmap cases you mentioned?
