- * In an attempt to see what might be going on inside CRTDLL, this program
- * walks the exception list after creating a new thread with _beginthread.
- *
- * It turns out that _beginthread DOES install an exception handler, as
- * expected, but this handler is NOT exported by CRTDLL (it is certainly
- * not _except_handler2 or _XcptFilter)... an odd and unpleasant turn of
- * events.
