It should be doing the rebuild in parallel -but- the IO is done synchronously.
Is this happening when you've rebooted? FreeBSD does a background fsck on startup
and this may be interfering. Check the output of ps -auxw to see if fsck's
are running.
I took a look at this over the weekend (whilst looking at other stuff in the
storage code) and I could -probably- make the AUFS swaplog parsing case much
faster. I've just got other priorities at the moment (ie, lots more cleaning up
before I start breaking things in creative ways.)
