Comment (by gk):

 We have #21675 for `window.navigator.hardwareConcurrency` now. While it
 would be neat to deal with "leaking the number of cores" once and for all.
 Defending against the probabilistic approach mentioned in this ticket
 might be harder than dealing with the low hanging fruit in #21675. Hence
 two tickets.
