It seems that if a trap handler for a terminating signal resends its
own signal (after resetting the signal disposition), any configured
EXIT trap will be executed (as I think is expected), but only if an
EXIT trap had already been set prior to the the first instance of a
trap having been set for the terminating signal in question.

If the shell is handling a terminating signal and receives another instance
of that signal while doing so, it takes that as an indication to exit
