Description
The tests consisted on successive stop/start and isolate/rejoin commands executed on 1 node, repeated 5-10 times.
The stop/stat test went fine, but we have observed instability of the functionalities testing the isolate/rejoin, sometimes it works and sometimes it doesn’t.

Fix for MariaDB branch pushed in revision: http://bazaar.launchpad.net/~maria-captains/maria/maria-5.5-galera/revision/3410
Setting wsrep_provider=none hangs in mariaDB build.
Problem seems to be that closing slave applier thread does not broadcast COND_thread_count. Strange thing is that MySQL version works well, although the relevant code path seems to be identical.
MySQL version bug is tracked here: https://bugs.launchpad.net/codership-mysql/+bug/1208493
