As a follow up to myself, I think I figured it out using an array popups 
to collect the markers into as I make them and then removing them from 
the layer, destroying the events and finally the markers. If this is not 
correct/complete, or leaks (How do I check if this leaks?), please let 
me know so this thread is complete and might help others.
