This is the output of mount :
As you can't see, we have a little use of nfs...

OK. Actually looking at the names of clients in that directory, I guess
you've seen some a few hundred thousand of them; divide that into a gig,
and it looks like we're leaking a few K on each mount.
That's weird. Well, it'd probably be easy enough to reproduce:
while true:
mount some nfs filesystem
unmount it
and watch idmapd.
