Code review comment for lp:~sergei.glushchenko/percona-xtrabackup/BT30559-kill-long-selects

Alexey,

I made required changes. Also I removed two documentation items, which turned out to be a garbage.

 =item --ftwrl-wait
and
 =item --ftwrl-wait-timeout=SECONDS

I run test locally and, re-pushed the branch, but did not start Jenkins build.

Thanks,
Sergei.
