- Add a mutex to protect the softc. - Use callout(9) instead of timeout(9). - Consolidate duplicated detach routines into a bus-independent detach routine. - Add an extra sleep lock flag (MSESC_READING) to prevent other readers from reading while the first reader is copying data out of sc_bytes[] via uiomove(). - Use bus_*() instead of bus_space_*().

* bus mouse interrupt, but that would require hacking in i386/isa/icu.s.
