Steve -- despite the hurry you are in, please discover that Mauricio and 
me did actually agree with each other.

We agreed that in both versions that you presented, the new ruby object 
would be GC'ed. For me, and concerning your second example, this was a 
new discovery. But I admit you have a point there, and your concerns 
were justified.

However, we both also posted a workaround for your second example, 
involving a helper function. It happened to be the exact same workaround 
in my and Mauricio's posting. (We even gave the same name to the helper 
function ("do_stuff") in both cases.)

With this workaround, your object will not be deleted by the gc.

P.S: As for your new example code and explanation, I have no idea what 
you mean by (several?) ruby scripts that may share ObjNodes. What is, by 
your definition, a ruby script? I would think script is a synonym for 
program, but obviously this does not apply here, since you want to share 
objects between them, while two programs would run in distinct processes 
and thus distinct address spaces.
