On debian systems at least, there's a program called 'tmpreaper':
This package provides a program that can be used to clean out temporary-file directories. It recursively searches the directory, refusing to chdir() across symlinks, and removes files that haven't been accessed in a user-specified amount of time. You can specify a set of files to protect from deletion with a shell pattern. It will not remove files owned by the process EUID that have the `w' bit clear, unless you ask it to, much like `rm -f'. `tmpreaper' will not remove symlinks, sockets, fifos, or special files unless given a command line option enabling it to.
