Best route to lock Chrome in memory kitkat? topic

Im looking for the best route to keep Google Chrome locked in memory. When I'm using my phone its 90% web browsing with multiple tabs in chrome open. I multi task alot and when switching to a different app like the play store and going back to Chrome, the site i was on sometimes reloads which i hate. i want chrome to stay locked in memory unless i close it manually. at most i might have 2-4 apps open including chrome. If it helps I have 3c toolbox pro installed and have access to build prop edits, oom settings, etc with that app. I of course am rooted on 4.4.2 deodexed rom stock kernel. 1 gb ram. Also have xposed framework and es file explorer.

Thanks in advance
Josh
