Reviving thread...

I have an initial patch in webkit (http://trac.webkit.org/changeset/77394)
and the chromium work is underway - I wonder what might be a good approach
to drive the apis closer together towards a real spec that everyone is happy
with?

There seems to be a lot of general agreement here (at least in principal :-)
that this is needed. We'll be doing a bunch of experimentation once this has
landed in chromium.

Cheers!
