That must be a fairly recent change--introduced in 5.0?  I did a quick
perusal of release notes of the releases since then--for i386--and
couldn't find any mention of any VM changes.

Are you really seeing the Linux like behavior of allocating every last
drop of RAM for a file system cache on a FreeBSD box?  On my venerable
4.5-RELEASE (about 2.5 years old) box, top reports:

last pid: 79233;  load averages:  0.07,  0.02,  0.01   up 232+23:39:02
02:22:40
19 processes:  1 running, 18 sleeping
CPU states:  0.0% user,  0.0% nice,  0.0% system,  0.0% interrupt,  100%
idle
Mem: 8580K Active, 169M Inact, 67M Wired, 8K Cache, 61M Buf, 256M Free
Swap: 50M Total, 50M Free

Running du / && /usr/libexec/locate.updatedb didn't really change those
numbers.

Cheers,
