More evidence of a possible memory leak in 2.2-STABLE-2 ?

As if to confirm Henrik's suspicion of a memory leak in 2.2STABLE-2

     After 4 days uptime since the last crash.

     Total in use: 62819 KB
     Total accounted: 43532 KB

which seems a reasonably significant discrepancy to me....

Any comments?
