Try the following experiment.

Copy Object>>shallowCopy to Object>>monitorShallowCopy

and after the pragma add...

     Smalltalk at: #Monitor put: #Failed.

Then in Playground...

    lastfail := 0.

    1 to: 100000 do: [ :n |  

|src copy|

src := Array new: n.

Smalltalk at: #Monitor put: #Succeeded.

copy := src monitorShallowCopy.

(Smalltalk at: #Monitor) == #Failed ifTrue: [

Transcript crShow: n; tab; show: n - lastfail. 

lastfail := n.

].

].

Produces the following interesting result....
