[removed] How to know if a connection with a shared worker is still alive?

PortCollection would come in handy but doesn't seem to be implemented in any browser.

It acts as an opaque array of MessagePort objects, thus allowing the objects to be garbage collected when they stop being relevant, while still allowing scripts to iterate over the MessagePort objects.
