           Summary: Specification should be clearer about when the
                    downloading of the application cache starts. "These
                    events are delayed until after the load event has
                    fired." is a bit misleading. The chrome developer team
                    interprets it as: Start downloading all resources f

Comment:
Specification should be clearer about when the downloading of the application
cache starts. "These events are delayed until after the load event has fired."
is a bit misleading. The chrome developer team interprets it as: Start
downloading all resources from the manifest file as soon as the page loads,
but just delay the events until onload event has been fired. The Firefox team
is actually delaying the download of all resources from the manifest file
until the onload event has been fired. Outcome in Chrome: Delay between
ondownloading and oncache event is minimal(in my testcase 34ms) and in firefox
the actual time it took to download all resources. Chromes approach makes
these events basically useless, because they are almost at the same time and
appcaching is not cancelable. With a better specification, this issue could be
solved.
