Syscall spamming is one of the main reasons why computers get slow when many apps are running.

Good software does not do that; when idle, it should only consume RAM, not CPU.

Aside: Browsers, and Electron, seem to always syscall-spam no matter what, which is probably a key reason why people feel that all Electron apps bog down their computers. When your computer gets faster, the software just does more syscall loops per second, for unchanged misery.
