I did some investigation with this.  At least I don't see any lingering
process from meson, but it does take time for the tests to die when I
hit CTRL-C, and I get a warning - I found this related bug:
   https://github.com/mesonbuild/meson/issues/2281

I guess it could be some kind of interplay between the way meson kills
tests?  Looking at the commit that eventually 'closes' the bug, they
merely set a flag rather than pass a kill signal down, so I guess it's
probably never going to be immediate.
