No, it's not.

/**
  * Compare two thread id's
  * @param tid1 1st Thread ID to compare
  * @param tid2 2nd Thread ID to compare
  * @return non-zero if the two threads are equal, zero otherwise
  */
APR_DECLARE(int) apr_os_thread_equal(apr_os_thread_t tid1,
                                      apr_os_thread_t tid2);

This behavior is by design, use the designated comparator.
