Well, this is what FHS says (in an ideal world it would reflect reality)

    Programs must not assume that any files or directories in /tmp are
    preserved between invocations of the program.

    IEEE standard P1003.2 (POSIX, part 2) makes requirements that are similar
    to the above section.

    Although data stored in /tmp may be deleted in a site-specific manner, it
    is recommended that files and directories located in /tmp be deleted
    whenever the system is booted.

Just mentioned it as one possible solution to the problem at hands.
