I just got a snip into my amavisd's 5 children /proc/<pid>/smaps file,
summing together the count of Private_{Clean|Dirty} pages.
I got this:
p1: 74,164 kb
p2: 70,772 kb
p3: 71,548 kb
p4: 74,064 kb
p5: 70,784 kb
This accounts for a total of unique 287,168 kB (say 280 MB?). ~ 56MB in the
average.
Sounds this good?
