Hi.

Now you should first create DebugSession:

debugSession := Processor activeProcess newDebugSessionNamed: 'Code simulation error' startedAt: self.
Smalltalk tools debugger openOn: debugSession withFullView: true.

What is the replacement for...?
�� �� [ Smalltalk tools debugger
�� �� �� �� �� openContext: self
�� �� �� �� �� label:'Code simulation error'
�� �� �� �� �� contents: nil].

In adding support to simulate new OwnedLock primitives, I see this is sent from
Context>>doPrimitive:method:receiver:args:
but this is no longer in the image.�� I can update it as I go.
