You probably want to get:

	http://www.freebsd.org/~terry/testset.txt
	http://www.freebsd.org/~terry/testset.tar.gz.uu

Which is a test toolkit that knows how to detect kernel memory
leaks over a series of system calls used to exercise various
code paths.

The sample implementation looks for namei() path buffer leaks; I
used it to verify the nameifree() code before I submitted it the
first time.
