+ <owner>csharrison@chromium.org</owner>

+ <summary>

+ The time between preload discovery and when the resource is actually

+ referenced. This is implemented by marking when a preload is discovered by

+ the scanner, and when it has its first ResourceClient added to it. Note that

+ for link rel preloads, this tracks the time from scanner discory to DOM

+ discovery of the link declaration, not the actual resource.
