[Pharo-dev] preferred way to invoke debugger

[Ben Coman]

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.
