示例1: restartSlavesExternal

recorder := concurrency.AllErrorRecorder{}
wg := sync.WaitGroup{}
swrd := actionnode.SlaveWasRestartedArgs{
Parent: masterElectTablet.Alias,

// ContinueOnUnexpectedMaster: continueOnUnexpectedMaster,

// The following two blocks of actions are very likely to time
// out for some tablets (one random guy is dead, the old
// master is dead, ...). We execute them all in parallel until
// we get to wr.actionTimeout(). After this, no other action
// with a timeout is executed, so even if we got to the
// timeout, we're still good.
