My reading of the presence of "exec" there was:
We're assuming that the current shell may not be to our liking, so
there seems to be little point keeping it in memory solely so it can
at worst somehow get in the way of a clean exit.
Does that really need a comment? I'm not sure I can make a succinct
explanation of what's going on for anyone that doesn't already know what
exec does. Feel free to make suggestions though.
