Unless something has changed very recently, most of the schedulers are
considered "experimental" and have known bugs.  The only one that I know
is stable is SCHED_4BSD.  Apparently, SCHED_ULE has some nice performance
improvements when it's not causing panics.

If you're not interested/capable in doing kernel debugging, you probably
want to go with SCHED_4BSD.  It would appear that some day SCHED_ULE will
replace it, but not yet.
