    Well, if the card is working properly, then you don't need the timeouts
    at all. Clearly, if they are needed, then either they should be more
    realistic in length (1/10th isn't bad, but 20 seconds?), or after a
    "reasonable" short timeout, it should sleep for an interval and check
    afterwards. Sucking all CPU for 20 seconds and locking everything else
    out isn't an acceptable method IMHO.
