Funny you should mention it, because you don't even need a large partition
to do that ... my 400 gigabyte partition (sorry folks, 400 GB is _not_
large) requires this:
add the line: kern.maxdsiz=3D"1024000000" to /boot/loader.conf
So anyway, not only are passes > 2 possibly useful, you don't even need a
big partition to have them be possibly useful ...
