My understanding on this memory leak issue is as follows:
IE deletes items from its memory when it has no references from
anything else left
If you have a class instance such as an autocompleter which has a
reference to a dom element, and that dom element references back to
the autocompleter, you have a catch 22 situation - they reference each
other so won't be deleted, but yet nothing else references them when
the user is viewing another page.
So the situation you mentioned isn't a problem, as long as you don't
store the autocompleter on the element.
I'm not 100% on this but that's what my knowledge on the subject is.
Of course you can use task manager to observe IE's memory (this will
only be an issue on IE) and see if repeated visits to the page
continue to increment IE's memory allowance. Andrew Dupont in his
prototype book recommends a mixin such as Trackable which statically
tracks all instances of a class, as this.constructor from within an
instance refers to the class of that instance. I won't post the code
here out of respect but it's the best approach to take.
