It shouldn't have reached this much in the first place.

Please note carefully that in my email I was comparing top's output to
cachemgr's:

  4243 squid 29 20 0 1325M 1317M kserel 42:39 0.00% squid
     Total accounted: 763252 KB

and asking if the difference was to be expected, or there could be some
memory leak of some sort. Even though Squid does not account for every
possible byte of memory, about twice as much is way too much, as Henrik
once noted.
