[OpenLayers-Dev] Memory leaks

   I am a ka-maps user. Recently, I noticed memory leaks (I used Process
Explorer for windows) in FF2 while navigating maps in my ka-map application.
I decided to conduct the same test with Google maps and found similar
results. The memory does get released if refresh the page, however there is
some evidence of leaks caused by circular references in Javascript as not
all page memory is released as the page refreshes. I then decided to conduct
the same test with the OpenLayers demo found in the main page of the
website. Again, I noticed the same problem. Example, FF2's memory usage is
66 mb when i first view the map. As I zoom in and out, the usage keeps
jumping till I had about 200 mb of memory consumed by FF2. Has anyone
noticed such a problem?
