workers

Looking at sticky activation it seems to be calling current high resolution time without a global (that is needed in order to know the time origin).

It'd be good to pass along the global. (W or window, if I'm reading the algorithms correctly)

I know this is specific to web workers, however I think this could be adapted to work for service workers. I was looking to create a separate plugin but the code would be mostly the same.

Looks like it scans the AST for a keyword (Worker) and generates an entry for the referenced file.

// web worker
new Worker('./foo.js', { type: 'module' })

// service worker
navigator.servi

Is there a way to make a job re-occur N milliseconds after it finished previous time?
