Yeah, a lot of the context is in that bug, and also in hallway/email/rietveld
discussions with Darin/Mike/Mads/Dimitri and others.

Hiding the tab has its own issues (i.e. what if an alert/prompt/showModalDialog
is shown?), and also doesn't fix the navigation use case.

As I mentioned in the crbug thread, this isn't meant as a fool-proof
workaround, since that's a losing battle (i.e. sites can just compute primes,
or register a thousand handlers to defeat any limit on an individual running
time/cycles of a handler).  This bug is a testament to what web developers will
do to workaround any browser limitations.  The result is a much worse user
experience.

This is only a stop gap until we have <a ping>, which I'll be looking at soon.
