- Added support for keeping track of load times.
For each document loaded we record the time the page was requested by the user
(or as close as we can get to that), the time the load process started, the time
the
document and it's dependent resources (scripts) have been loaded (before
onload())
and the time all the document's resources have been loaded.
We use this data for two things:
1) We histogram the deltas between the time marks
2) We expose the times to javascript running on the page which was loaded
