Rails spinoffs - Jan 2008 - Prototype.js - Memory Management / Maintenence question

Hi, I had a question about deleting something from my computer memory.

I used a "Creative Div" tag and I used "Remove" to delete
it, but it
doesnt completely delete from my memory;  even after I used a null
value.   Can you please tell me how I can completely remove this from
my memory.   Your help would be most appreciated.   Thanks!

Alcohol, lots of alcohol
(actually, sorry I don''t know, can you provide an example of where you
add
and remove the item, you may have a circular reference)

Setting it to null is the best you can do. The garbage collector only
runs on page refreshes (to my knowledge), so if you''ve built an
application that mostly involves the user sitting on one page and
having lots of Ajax performing DOM manipulation, then you have to be
extremely diligent about cleaning up objects/elements when you are
done with them.

I try to remove all my listeners, and set any internal objects
(arrays, hashes, etc.) to null before I destroy instances of my custom
classes.

If anyone has better advice than that, I would love to hear it, as
it''s been a constant battle for me lately.
