Code review comment for lp:~percona-dev/percona-patches/dict-size-limit

Vadim,

If a handler of certain table exists, we don't remove the dictionary entry
even if the hendler is not used.

So, we shouhld use "FLUSH TABLES" to close such handler

or use "small table_cache" to close such handler automatocally.
