yeah - if you watch to see what the process is actually doing it spends
a lot of time looking for <foo>.meta files, <foo>/meta/, and all of
those things. I think (from vague memory) that each file results in 5
or so stats() of the directory (each of which will take a long time for
your classic UFS based directory with lots of files in it.)

You basically need to track down the features that check all that stuff
and turn them off for your mirror directories.

(Can't give any more specific pointers than that, cos I never got
around to looking further at the problem.)
