Seeing as you seem to be concerned with the security of this.... The first question is, "is this running as root?". If so, I see multiple problems:

Here's the lowdown, I'm a mischievious (sp?) user, and I see the source to this program. Knowing the name of $tmp_dir I do the following:

$ ln -s /etc /tmp/blahblah-MM-DD-YY

In your program you say, "hmm, does /tmp/blahblah-MM-DD-YY exist?".
Why yes, it does.
You say, "okey dokey rm -f /tmp/blah.../*".
I say "goodbye /etc/*!!".

If this isn't run by root, it's far less of a problem (unless they link to your home directory :). You really should always check if it's a link, hard or soft, who the owner is, etc.
