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