Interesting that we have not seen this as an "issue" in the past. I'd venture to say that this is a language issue (feature?) the programmer needs to be aware of and deal with accordingly. The same as adding objects to any container - a collection, thread local, etc. Parallels could even be drawn to passing object references into methods as parameters.
