> > This experiment enables:
> > - Use THREAD_MODE_BACKGROUND_BEGIN/END to set the priority of
> >   background threads. This affects memory and IO priority in addition
> >   to CPU priority.
> > - Increase thread priority to "normal" in scopes where background
> >   threads load modules.
> >
> > The expectation is that this will improve responsiveness of Chrome
> > (input delay, first contentful paint), without regressing jank.
> >
> > We are adding the testing config in preparation for enabling this
> > via Finch in M79.
