I can't speak to your underlying problem, but if you add an internal (or 
external) bitmap to your array, it speeds up rebuild time considerably.

At create time, you can use the " --bitmap=internal " option.  I know 
you can also add a bitmap to an existing array, but I don't remember the 
magic incantation at the moment (you can probably find it by searching 
the list archives - the topic has come up before).  Or google "write 
intent bitmap."
