    ****************************************************************
    A section of Purify code was not thread safe. In a heavily
    multithreaded program, there was a small chance of a Purify
    data structure being changed in one thread while another
    thread was searching it.
    

Problem conclusion

  • Added locking to prevent interference from other threads.
    

Temporary fix
