Nah, this must be some leak of another kind. Luckily I could bandaid
this by unionfs mounting an mfs disk over /tmp so programs continue to

But, tmpfs really is out of resources, as I cannot create new tmpfs's
for example:

root at elmar: ~# mount -t tmpfs tmpfs /media
mount: tmpfs : No space left on device

And besides, the /tmp mount comes up fine and shows enough free space (I
checked this the last time, after I had rebooted the box).
