Hm.  But there are programs which do _not_ _know_ the amount of memory
they will need.  For example, named keeps growing for several days.
As far as I understand, a process can still run into trouble even if it
touches its pages but needs to allocate more memory tomorrow or next
week.  If someome's Netscape has eaten up all memory by then... bang.

(No, nobody's running Netscape on our name server and nobody ever will.
That was just an example.)
