Ah. I guess this is a side-effect of the race between the disconnect and
the AM message. Because there's this code in `TaskSchedulerImpl`:
override def executorLost(executorId: String, reason:
ExecutorLossReason): Unit = {
var failedExecutor: Option[String] = None
synchronized {
if (activeExecutorIds.contains(executorId)) {
val hostPort = executorIdToHost(executorId)
logError("Lost executor %s on %s: %s".format(executorId,
hostPort, reason))
