Description Chris Dumez 2017-04-04 11:18:42 PDT 
Tweak how long we allow a process to go over its background CPU limit. We currently use a conservative 15 minutes but we should probably use something lower to prevent unnecessary battery drain.

What methodology are we going to use to evaluate these limits? Do we keeps statistics on aggregate kills, or on aggregate battery usage in the field?
