Determining process preventing umount of busy partition

[Polytropon]

Replying to my own message... I'm so stupid: How do I *use* lsof which
is /usr/local/sbin/lsof when actually trying to umount /usr? Can I
put a copy of it into, let's say, /root/bin? I've checked library
dependencies:

	# which lsof | xargs ldd
	/usr/local/sbin/lsof:
	        libkvm.so.4 => /lib/libkvm.so.4 (0x280a2000)
	        libc.so.7 => /lib/libc.so.7 (0x280aa000)

So this is on the / partition. This should work, am I right?
