That's actually a fairly standard trick, one that I've seen in other programs. The idea is that the invoking process should exit with the same status as the invoked process, even if the invoked process failed due to a signal. So my current guess is that that's why the Korn shell is doing what it's doing. It's just that this trick doesn't work for the shell itself, at least, it doesn't always work in the presence of traps.
