BB Bold 9700 :: High Memory Usage While Browsing?

Somehow my memory usage is so high the dang "processing" clock shows up every few seconds, literally.This happens after a few hours of browsing, and I should point that the whole time what I did was merely browsing, I didn't do anything else.

These are the applications running while I'm browsing:
1. Browser (well, duh)
2. Messages
3. Phone
4. Home screen
5. BBM
6. SMS Filter

According to MemoryUp Personal, the memory usage goes as high as 50%, that's around 100 MB memory consumed, for reading humor articles. I can only imagine what editing documents will do, maybe a new high score at 200 MB? No, seriously, does browsing actually use that much memory? Maybe I should also say that the memory consumption is gradual, from 39%, and then 40, then 41, 42, 43 all the way up to 52%, the current high score, when I decided 52% for a native browser is a true memory spending spree and pulled the battery. Before any humor reading, though, the usage is only around 10%, so 30% is already high enough, let alone 50.Just what is happening to my blackberry? EDIT: PROBLEM SOLVED. Turns out I was the dumb newb ranting about unnecessary things. As the Browser is used, it accumulates stuff in RAM, which can only be cleared by shutting it down, which is impossible due to it's nature except with battery pull. Thus the only way to go is to use another browser or use the native one sparingly, or pull the battery every few hours.
