Fix #822 - kqueue hang in suite 9. 

Priorly we only checked exactly one state when an event was received.
This was incorrect. A state may have a next state, an action to take
after the first in the list of states has been taken. This change
acknowledges that and makes the code work with the state list vs just
the head of the list.
