I'm busy too :-)

Probably either one is ok. OSProcess uses the #changed: #update: protocol
and in Cuis this is supported for legacy compatibility. If ActiveModel is more
efficient when using #changed: #update: then that would probably be better.
But Object will definitely work, so if you are not sure, then just use Object.

(FYI: At one time, I had updated OSProcess and CommandShell to use the "improved"
#when:send:to protocol. At that time, Squeak did not handle weak collections
well, and the performance was horrible. So I had to change everything back to
use the use the #update protocols. This was a lot of work for me, but the old
protocol is fast and efficient and I have not had problems since. So that is
why OSProcess uses the old protocol).

OK thanks.

Good, that makes sense to me. As you can see I am a newbie :)

Thanks I will try that. I think that there may be some carriage returns
embedded in strings in some of the source code, so I will need to check and
see if these are a problem.

Thanks for doing this. I am busy with the holiday season so I may not be able
to follow up quickly.

Happy holidays to all!
