Review Comment:
Basically what I am trying to say is that whether we should also consider
increasing wait time here, by say 500/1000 ms instead of 100 ms?
```
void triggerHeartbeatForTests() {
synchronized (ibrManager) {
final long nextHeartbeatTime = scheduler.scheduleHeartbeat();
ibrManager.notifyAll();
while (nextHeartbeatTime - scheduler.nextHeartbeatTime >= 0) {
try {
ibrManager.wait(100); <=== how about 500ms at least?
} catch (InterruptedException e) {
return;
}
}
}
}
```
