From efee39a075a3ce59864fe6e9e0d0a0c90f04f986 Mon Sep 17 00:00:00 2001 From: "jkummerow@chromium.org" Date: Fri, 9 Mar 2012 17:55:54 +0000 Subject: [PATCH] Profiler experiments: update flag default values. This doesn't enable the experimental profiler by default, it just tunes its behavior when it is enabled.
