prevent doing filter ops locking for staticly compiled filter ops...
This significantly reduces lock contention when adding/removing knotes on busy multi-kq system... Next step is to cache these references per kq.. i.e. kq refs it once and keeps a local ref count so that the same refs don't get accessed by many cpus... only allocate a knote when we might use it... Add a new flag, _FORCEONESHOT.. This allows a thread to force the delivery of another event in a safe manner, say waking up an idle http connection to force it to be reaped... If we are _DISABLE'ing a knote, don't bother to call f_event on it, it's disabled, so won't be delivered anyways.. Tested by: adrian
