Mozilla chews memory slowly. The system either gets slower until it's 
too painful, or it gets slower until oom goes mad.

It was pretty bad on RHL 7.3 which I used to run in 128 mbytes, and on 
occasion I found Moz "using" 700 Mbytes plus.

It still seems to happen, but I generally kill if for some other reason 
(eg it tends to loop and take all CPU).

Now, if I knew how to make postgresql take a little more. It's been 
running, loading a table, for almost two days on my laptop. Over 1 Gbyte 
RAM, pg's only using 11m res, about 20mbytes all up.
