>   
>   The fdc worker thread was using a one second timeout while waiting for
>   a new bio to arrive or for the device to detach.  However, the driver
>   already does a wakeup when queueing a new bio or asking the thread to
>   detach, so the timeout only served to waste CPU time waking up the
>   thread once a second just so it could go right back to sleep.  Use an
>   infinite timeout instead.
