The invention relates to a self-tapping screw with a head and an outer thread support. of from 8 to 25 mm^sec and a residual and de-asphalted oil component, and the use of said blend as part of a gear oil or a cylinder oil formulation, and other uses. The transmitter operates according to a first clock having a first clock rate, and the receiver operates according to a second clock having a second clock rate. In response to determining that the SBAL count is greater than one, a number of the SBALs from the queue and associated SLSBs equivalent to the SBAL count are prefetched without waiting for a notification of completion of each of the SBALs forming the IO request, and states of the associated SLSBs transition from adapter-owned to program-owned.
