Meaning an EventListener should be called even if another listener in
the list currently being processed removes it? I think the implementation
issue may become even more difficult in languanges with explicit memory
management though. Currently, my implementation frees a ListenerEntry
struct when removeEventListener is called. As is, this would result in
dereferencing a dangling pointer if dispatchEvent attempts to trigger a
listener after it has been removed. I suspect I must collect the pointers
to the actull functions to be called for each listener and store that
in an array (i.e. pre-dereference the listener functions).

I'm glad I asked.

Thanks Curt,
