Could this be named better? Maybe registerClientWebProcess() / unregisterClientWebProcess() ?

> Source/WebKit/UIProcess/Network/NetworkProcessProxy.messages.in:65

I think the naming could be better. Maybe RegisterServiceWorkerProcessClient() or RegisterServiceWorkerProcessClientWebProcess()

What's the benefit about doing this in the next run loop iteration?

waitUntilServiceWorkerProcessForegroundActivityState(webView.get(), false);  to be safe?

waitUntilServiceWorkerProcessBackgroundActivityState(webView.get(), false); to be safe?

I tried to explain this in the comment above.

WebProcessPool::updateProcessAssertions gets called at creation of the token, but the token is not yet assigned to WebProcessProxy.
If calling updateServiceWorkerProcessAssertion(), the WebProcessProxy will be seen as not holding an assertion although it will be just after.

Let's go with registerServiceWorkerClientProcess/unregisterServiceWorkerClientProcess
