What is the use case for this? It doesn't seem useful to me - to
invoke update explicitly, one normally needs to have UI anyway, at
which point it's much easier to call update() directly from a page.
A tangentially related question: what will happen to a SharedWorker
whose cache got updated? Will the repository use a new source for new
instances, while the old ones will continue to run? Looks like there
is a significant potential for mistakes here, as scripts won't
normally expect several instances of the same SharedWorker to be active.
