Has anyone seen Mozilla (mozilla-bin) leak big time like 600 MB and growing?

Weird, this morning I went AFK for like 10 hours (Xscreensaver running) 
and came back. I noticed my Linux workstation (Debian; Kernel 2.6.14-K7) 
was frozen, but still responding slowly.

I checked top (took a while) and noticed mozilla-bin was hogging over 
600 MB and growing. I had to kill its process to regain control over my 
computer. Has anyone seen this big leak before?

I know Firefox and Mozilla has leak problems, but nothing like this. Or 
does it exist? I remember I was on worth1000.com looking and rating each 
image on 
http://www.worth1000.com/cache/contest/contestcache.asp?contest_id=9161&display=photoshop#entries 
(requires an account). I also remember I only had two windows (one was a 
pop-up when viewing a larger image). Thanks goodness SessionSaver 
extension saved my session so I could resume it. :)

Has anyone experienced this problem before (doesn't have to be Linux)? 
Does Seamonkey v1.0 fix these memory leak issues?

Thank you in advance. :)
