    tests: GThreadPool free-function is not reliably called on FreeBSD yet
    
    This new feature in 2.69.0 does not appear to be reliable on the FreeBSD
    CI runners. Disable this part of the test while it's investigated,
    so that we can use CI as an acceptance gate for unrelated branches again.
    
    Leave it enabled when run with `-m thorough` so that FreeBSD developers
    can debug the intermittent failure.
