The P_SELECT flag was moved from p->p_flag to td->td_flags, but p_flag
was locked by the proc lock and td_flags is locked by the sched_lock.
The places that read, set, and cleared TDF_SELECT weren't updated, so they
read and modified td_flags w/o holding the sched_lock, meaning that they
could corrupt the per-thread flags field. As an immediate band-aid,
grab sched_lock while reading and manipulating td_flags in relation to
TDF_SELECT. This will probably be cleaned up some later on.
