 Additionally, if there is a bug in poorly written event receiver code there is no way to notify SharePoint the bug occurred and the event should be executed again.  You can work around this to some degree with event receivers attached to SharePoint lists.  See below for more information about this approach.
 
 - When an event receiver executes a significant amount of code an asynchronous pattern should be used.
