You may have found a problem. However, you need to know that allInstances is only truly accurate immediately after a full garbage collection. Therefore you should precede any such careful investigation by
Smalltalk garbageCollect.
Squeak does many frequent garbage collections which may or may not fully reclaim a given unreferenced object. This process is so effective that full garbage collection almost never occurs, so it can definitely look like there's a leak, even when there in none.
