Reviewed by Ben Nham.

Only disable the background responsiveness timer once the process has been
suspended. We wait a long time on macOS to suspend background processes so the
background responsiveness timer still is useful during this "running in the
background" period.

The background responsiveness timer had very recently been disabled on macOS
in 265536 at main.
