Just out of curiosity, would it even theoretically be possible to have
a browser free up all objects and references that are not references
anywhere else?
I'm just wondering: do these javascript implementations just suck, or
is it something inherent to the language and its definition?
At least the behaviour when using eval would be different. I could
have objects that are not referenced anywhere, yet eval some
user-input that does refer to them..
But other than eval is there an scientific reason its impossible to
implement decent memory management in these browser?
Anyone got any knowledge they would like to share?
