Flavio Junqueira updated ZOOKEEPER-1292:
----------------------------------------
Attachment: ZOOKEEPER-1292.patch
I have added more comments and changed the timeouts:
* I have reduced the 2s timeout to 0.2s. I have made this timeout long because
I wanted to make sure that if it hangs, then the chance of a false positive is
low. Given that the test implemented here is supposed to be more reliable, it
should never happen unless we run into a bug.
* I have reduced the 1s sleep to 0.1s. The idea of that sleep time is to
represent the time a follower takes to declare the leader dead. Removing that
sleep altogether means that a follower declares a leader dead right after
having elected it. I have run several times without it, though, and it still
works.

> reasonable test case.
