+1.

Should we document a polyfill, since the session GC firing logic can be
non-intuitive? Here's an attempt, anyhow:

function session_gc() {
    $initial = [
        session_status(),
        ini_get('session.gc_probability'),
        ini_get('session.gc_divisor'),
    ];
    if (PHP_SESSION_DISABLED === $initial[0]) {
        return false;
    }
    if (PHP_SESSION_ACTIVE === $initial[0]) {
        session_write_close();
    }
    ini_set('session.gc_probability', 1);
    ini_set('session.gc_divisor',     1);
    session_start();
    ini_set('session.gc_probability', $initial[1]);
    ini_set('session.gc_divisor',     $initial[2]);
    if (PHP_SESSION_NONE === $initial[0]) {
        session_write_close();
    }
    return true;
}
