    # TODO FIXME (aseipp): keep the timeout limit to ~15 minutes. this is long
    # enough to give us runway for the future, but also once we hit it, we're at
    # the "builds are taking too long" stage and we should start looking at ways
    # to optimize the CI.
    #
    # at the same time, this avoids some issues where some flaky, bugged tests
    # seem to be causing multi-hour runs on Windows (GPG signing issues), which
    # is a problem we should fix. in the mean time, this will make these flakes
    # less harmful, as it won't cause builds to spin for multiple hours, requiring
    # manual cancellation.
