Base event manager that handles adding/removing listeners | |
and firing events. Meant for high concurrency. This class is | |
reentrant-safe; listeners can be added and removed by other listeners when | |
they receive events. The changes will not be visible until the event fire | |
that initiated the recursive sequence of calls completes, however. | |
