Possibly, but the changes I made already have us partway there by using threadControl_onEventHandlerEntry(). I still want to look into a few things. It's no clear to me what happens w.r.t. the debugger setting up event requests after the connection is established. For example, is there a potential timing issue that can lead to the ExceptionEvent being sent too soon.
