This patch (as1621) removes the limit on the number of loops allowed in hub_tt_work(). The value is arbitrary, and it's silly to have a limit in the first place -- anything beyond the limit would not get handled.
Besides, it's most unlikely that we'll ever need to clear more than a couple of TT buffers at any time.
