// CBA: if opera has memory cache set to automatic it will not free memory until it eats up some percentage of available system memory
//	- in my test, with 512mb, it went up to 75mb, so, the percentage seems to be about 15%
//	also, even tho Opera seems to leak, it appears it's hogging ram only if you have a lot of it :)
