I don't know how, but somehow something is holding references to
the removed files causing them to fail to be reclaimed.

Could you run your system for a while to build up a new set of
these files, then run a script with the `df -ih' as before. Then
run `vmstat -m', `sysctl debug', and fstat -f /usr' both before
and after doing the umount/mount. Hopefully that will give us
some more clues as to what is happening.

And Jeff, if you have any ideas do speak up :-)
