Hi!
It looks like that we are currently suffering memory leaks.
That is a bit strong a statement.
Maybe some IDE UI stuff might sometimes hold onto something too long.
In march 2015 it was said in the mailing list:

I also tried this:
1. Create a dummy class:
Object subclass: #AAA
instanceVariableNames: 'x'
classVariableNames: ''
category: 'AAA'.
2. Open a Playground and do it and go on this:
a := #AAA asClass new.
And why would you do that ?
You assign to a workspace variable, hence your object is held in the scope of the
Playground.
So whenever the Playground gets retained by some other object, like an announcement, event
or whatever, your object get retained too.
I am 100% sure that if you do
1e6 timesRepeat: [ #AAA asClass new ].
3 timesRepeat: [ Smalltalk garbageCollect ].
#AAA asClass allInstances isEmpty.
=> true
3. In the second pane go on "self"
4. Close the Playground
5. Execute:
3 timesRepeat: [ Smalltalk garbageCollect ].
6. Check:
#AAA asClass allInstances.
7. Repeat if necessary, and after a while, the result after step 6 is not empty.

The problem is still present.
Looking at the pointers
There was an object reference crawler no? I remember someone worked on this? I tried
sending #pointersTo but I without much success on identifying the cause of this leak.
Any idea?
Cheers,
Alexandre
