Does anybody knows something about the status of the change
in Context(Part) runUntilErrorOrReturnFrom:

eliot proposed a change (something about dead sender contexts)
(years ago :)
I don't see this version in current squeak 4.5 images.
This change is in the current pharo image but it givves some strange
behavior while debugging block returns.

13271 <https://pharo.fogbugz.com/default.asp?13271> inconsistent behaviour
when debugging

Stepping over this code will show the inspector, although the debugger
should return in  the ^self send block .
[ ^ self ] value.
^ 1 inspect.
