I did a quick test which confirmed that the opens get closed when the "nocache"
option is used on the nullfs mount as well.

Kostik, I think your patch is a good idea and you can consider it reviewed by me
if you'd like.

I also did a quick test wth unionfs and it did not accumulate opens, so it 
seem to suffer from this problem. (It does have issues, as noted by the BUGS
section of the mount_unionfs man page.)
