This error message means "There is no event handler of the type specified"
according to page 73 in the SunView System Programmer's Guide.

Since one could do this in SunView, the ttysw would register a default
notify_set_wait3_func() on the tty's child process, this would be a bug.
The workaround is to use the function notify_set_wait3_func instead of
notify_interpose_wait3_func.
