SkinnablePopupContainer.open() -> close() -> increases System.privateMemory

[Frank Dahmen]

Hi,

see subject, i think I've cleaned up the popup
i also did a test with a clean (empty) SkinnablePopupContainer.
privateMemory goes up, not eyery time, so i think it can be 
destroyed.... but only sometimes????

opened and closed 10 times:

System.privateMemory: 53784576
System.privateMemory: 54345728
System.privateMemory: 54910976
System.privateMemory: 55443456
System.privateMemory: 54837248
System.privateMemory: 55447552
System.privateMemory: 55934976
System.privateMemory: 56307712
System.privateMemory: 56418304
System.privateMemory: 56414208


or is System.privateMemory not the right value to look at?

thanks
