Any time you have to perform a similar cleanup for multiple code blocks,
you might consider using the goto statement. It's there for just this
kind of thing. Put the cleanup code at the end of the function after a
label, and then anytime you need to abort and clean up, just goto that
block. It's very clean and readable to do it this way. The Linux
kernel source uses this technique a lot.
