Log Message
Inaudible background tabs should become eligible for memory kill after 8 minutes
https://bugs.webkit.org/show_bug.cgi?id=170574
<rdar://problem/31488686>
Reviewed by Gavin Barraclough.
Lower the delay for potentially marking background tabs as inactive from 60 minutes to 8 minutes.
Letting a tab misbehave in the background for an entire hour was overly charitable.
