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.
