none of firefox, chrome micromanage to this extent, that's exactly the point as for the second question, it's conveniently ignoring keep-alive and *anything* interactive. re-aquiring fds *and* emptying the queue of pending actions is the cost, not the mere syscall apparently you or claudio came up with a scheduler that guesses which tabs are more important, swaps to disk the ones that aren't, and pretends their ongoing transmissions don't mean anything
