WebPositive doesn't free memory after closing the tab.

[mr.Noisy]

Hello! This is hrev40200 GCC4/Hybrid, WebPositive hrev573.

How to reproduce:

1. Open ​http://shpilenok.livejournal.com/ and some pages linked from there.
2. Check used the memory in ProcessCotroller. It was about 415 Mb in my case.
3. Close all tabs, except one blank.
4. Check used memory again. Values does not changed.

For me value of used memory with few open tabs reached 1400 Mb (!)

I've noticed that WebPositive uses more and more memory when left unused. I had one tab open (Facebook) over night and WebPositive went from 30,6MB usage to 96MB.

I've also noticed that when closing a tab, memory usage increase.

Well it's entirely possible that there are memory leaks in WebPositive / WebKit, but the way you're testing things isn't correct. The memory is used for caching so that the next time you reload the page it's way faster. You actually want the gigabytes of ram you bought with your computer to be used for something :)

For example, if you close a tab and reopen the same url again in a new tab you'll see that the memory usage doesn't increase, because it reuses the cached data in memory.

As for the facebook test, as the page updates itself, it probably cached more data overnight and it again doesn't prove that there is a problem.

I've tested in the old Web+ also and it looks ok. It's also possible that the recent Webkit update fixed some leaks. In any case, i'm going to close this ticket as invalid, but anyone feel free to create a new ticket with a better testcase.
