[Pharo-dev] Memory leaks with Spec?

[Stéphane Ducasse]

Hi guys

this is strange I cannot get rid of Spec based ui instances.
I tried many 

LoggerUI allInstances do: [ :each |
        SystemAnnouncer uniqueInstance unsubscribe: each ]

LoggerUI allInstances do: #delete.

Smalltalk garbageCollect

Nothing changes. Each time I create and close it does not get garbage collected.
I remove all the announcement registration from my code but nothing changes.
