I leave my browser running for days, and have noticed OW using upward of 1GB of total memory at times, which I thought was a bit odd, so I decided to track it yesterday. Below is the output from top and it's clear that OW is slowly grabbing more and more memory.
I would expect OW's memory needs to grow as the number of pages I'd viewed increases due to caching etc. but I would also expect that cache to empty once in a while. I can see that if I open many pages and then close them again, it frees up most of the memory used, but it doesn't free it all and the net result is that it keeps munching away at memory.
Any ideas?
