New Revision: 227980

  Move to SCHED_ULE by default. Since r226057 SCHED_ULE and sparc64 are
  compatible with each other and since r227539 the last issue seen when
  using SCHED_ULE is fixed. At least on UP and 2-way machines SCHED_4BSD
  still performs better than SCHED_ULE, however, the optimizations done
  in r225889 pretty much compensate that so there's at least no net
  Thanks go to Peter Jeremy for extensive testing.
