Well, limits are nice if you can predict your usage in advance.

In my case I was using an unlimited mfs (as I have for years):

/dev/ad0s2b            /tmp            mfs     rw              0       0

I seem to remember some changes to mfs a while ago and (without
checking cvsweb) I assume that's when this:

     -s size
             The size of the file system in sectors.  This value defaults to
             the size of the raw partition specified in special (in other
             words, newfs will use the entire partition for the file system).

became the default behaviour.

This seems a bit of a pain.

Is there anyway to go back (if I'm correct) to a dynamic swap user.
I suppose I'm talking about a real tmpfs ?
