At what point in the Document creation process / lifecycle does this object get
instanced and later disposed? I'm gonna assume its lazily created on first
access to 'navigator' (or something there abouts).

I'm thinking a better 'owner' for the Provider is ultimately somewhere in the
loader classes, and this object that provides scriptable API could access it
thru that owner which establishes ownership early on.

This looks like an ok way to hook things up so that it work for just script
method calls for now, but at some point soon'ish i'll probably need to give it a
new owner, probably DocumentLoader, and ensure it's instanced prior to
DocumentLoader::startLoadingMainResource() time.

Does that make sense?

One thing that doesn't work out for that is having the
WebServiceWorkerProviderClient interface be implemented by this class since it
won't be created till some time long after startLoadingMainResource time.
