Comment:

 Thanks David. As caching was added during the current release cycle, I've
 moved it on to the milestone for investigation.

 The placeholder value is stored in a static variable so I am not sure how
 to test for this.

 The issue is limited to sites with a persistent cache, potentially
 stuffing them with keys they can never access again.

 I like the options you provide: protentially the best way forward is to
 skip LIKE queries for now and revisit in 6.2.
