-   * Tests message project watches on new patch sets
-   * <p>
-   * As of 2015-06-21 this test is marked flaky for triggering race
-   * conditions between indexing and project watches filters as
-   * of 2015-06-21.
-   * <p>
-   * The test $SOMETIMES fails, stating that 2 emails instead of only
-   * 1 got sent. The root issue is the inserting of two patch sets
-   * (one shortly after the other), where the first patch set would
-   * not match a user's filter while the second one would.
-   * <p>
-   * The test basically:
-   * <ol>
-   *   <li>Sets up a watch on the text 'sekret' in the commit message.</li>
-   *   <li>Pushes a change without sekret in the commit message (no
-   *     email is expected). (We'll refer to this as PS1)</li>
-   *   <li>Push another patch set to the same change with sekret in the
-   *     commit message (1 email is expected). (We'll refer to this as PS2)</li>
-   *   <li>[...]</li>
-   * </ol>
-   * <p>The expected flow of actions for step 2+3 is:
-   * <pre>
-   *    (i) Write PS1 to the index
-   *   (ii) Send out emails for PS1 after checking project watches from
-   *        fresh ChangeData
-   *  (iii) Write PS2 to the index
-   *   (iv) Send out emails for PS2 after checking project watches from
-   *        fresh ChangeData
-   * </pre>
-   * <p>
-   * But as step (ii) and step (iv) happen on separate threads, steps
-   * (ii) and (iii) might get turned around and become:
-   * <pre>
-   *   * Write PS1 to the index
-   *   * Write PS2 to the index
-   *   * Send out emails for PS1 after checking project watches from
-   *     fresh ChangeData
-   *   * Send out emails for PS2 after checking project watches from
-   *     fresh ChangeData
-   * </pre>
-   * <p>
-   * Hence, the filters for project watches for the emails for PS1 query
-   * the index after PS2 has already been written there. Hence, the
-   * filters for PS1 use the commit message of PS2 when filtering on
-   * 'message:sekret'.
-   * <p>
-   * Since in the ProjectWatchIT test, PS2 contains 'sekret', the filters
-   * for sending out emails for PS1 see a commit message containing
-   * 'sekret', and the watches match for both PS1 and PS2, although they
-   * should only match for PS2.
-   * <p>
-   * This explains why the test is only failing sometimes, and also why it
-   * is more likely to occur when the system is under load.
-   * <p>
-   * A demo exposing the race condition is available at
-   * <a href="https://gerrit-review.googlesource.com/#/c/68719/1">https://gerrit-review.googlesource.com/#/c/68719/1</a>.
