We would like to thank Professor J. Labarta and X. Martorell for all their help. Their interesting comments increased the quality of this work significantly. We are also grateful to E. Artiaga who helped us with some of the benchmarks used in while testing the proposed mechanism. Finally, we are also in debt to J. Fischer and E. Youngdale, which had the patience of guiding us into many important details of the SCSI driver for Linux.
