I would love to get rid of the j_state_lock, but looking through the
code, I couldn't figure out how to do this safely. Hence my
conversion of the j_state_lock to a rwlock_t, with the downside of
this causing more cache line bounces. If someone can suggest a way to
drop needing a global spinlock (whether it is an exclusive or rwlock)
in start_this_handle(), I'd love to hear them.
