The default meson timeout is 30 seconds which is enough for these
tests. Of course larger timeouts give more headroom.

If running on particularly slow environemnt (eg under TCG)
then it would be expecte dto instead use "meson --timeout-multiplier=10"
to make everything have more headroom.

So I wonder what threshold we need the extra headroom above
30 seconds in the default config ?
