  12 // There are several limitations to this checker:
  13 // - It assumes that this client is the only one committing at this time.
  14 // - It relies on the test-only 'self-notify' to trigger an extra GetUpdate
  15 //   cycle after every commit.
  16 // - It's flaky.  In some rare cases, the IsExitConditionSatisifed() call could
  17 //   return a false positive.  See comments in the .cc file for details.
  18 //
  19 // Because of these limitations, we intend to eventually migrate all tests off
  20 // of this checker.  Please do not use it in new tests.
