A larger set of functions should cause the result of a SELECT not to be cached.

With selects=verify_cacheable, the cache will not store the resultsets of SELECTs that use functions or fields that are not cacheable; e.g. CURRENT_TIME(). However, it does not detect all functions that could be detected.

A workaround is to create an unlike rule that causes SELECTs that use a particular function not to be cached.

Futher, the cache should also not cache the result of SELECT ... FOR UPDATE and SELECT ... LOCK IN SHARE MODE.
