Thanks for reporting. Is this patch about to reduce a warning only?

I'd say - mostly. OTOH one comment son the origin reports says :

>I wrote "this will leak" for a good reason. It does leak, forgetClient() can >only do some basic cleanup (forgetting this client, like the name says) but not >delete associated containers, that caused crashes (e.g. when they were being >deleted already).
