We do not need to see that you are just as human as other developers
and are prone to make mistakes that you need to fix it in a
follow-up.  In other words, please do not introduce a bug in [1/2]
only to be fixed in [2/2].  By squashing these two patches into one,
you can pretend as if you are a perfect developer and never leaked
memory ;-).

But as I said, I do not see a need for this helper function in the
first place, so...
