I actually think it was a good intention of yours and I would agree
with the patch.  The automated tools that find and complain about
these issues do not know about our local house rules like "do not
bother freeing immediately before exit" and will keep notifying us
of leaks. One way to reduce the noise level so that we can focus on
real issues they may find for us in the future is to squelch these
"uninteresting" ones by "fixing" them, even if our local house rule
says OK, like this patch does.

I said "a lot less interesting" and did not mean "it is bad for our
code to do this".

Thanks.
