Yes.

Here's what I plan on doing:

Run 1:
	Out of the box.  No special flags to mount or /etc/make.conf
Run 2:
	Mount /usr/src and /usr/obj async,noatime
Run 3:
	-pipe
Run 4:
	async,noatime and -pipe

I'd like to run separate disks tests, but I don't have a second hard
disk that is suitable for this sort of thing.  So I can't do ccd tests
either.  All runs will be one the same, arbitrary source tree.
