    Bug 619031 - method-calls-in-thread test failing
    
    The test was assuming that g_timeout_add() waited for at least the amount of
    time given to it before running the function.  This is not the case -- the
    function can be run as much as 1ms early.  Make the lower time bound asserted
    in the test more permissive to account for this.
