" Sessions could end up deadlocked when executing a combination of SELECT, DROP TABLE, KILL, and SHOW ENGINE INNODB STATUS. (Bug #60682, Bug #12636001)"
Even though this is present in 5.5.27 changelogs, it (commit: http://sprunge.us/AYKP) seems to have been null merged (so without changes) into 5.5.x tree. So, either it is not fixed in 5.5.x or not required there; not sure if this requires a separate bug report.
Also, for bug mentioned in #27 --
