   “has a fault in its garbage”

   Jim always had a way with words.

   No it’s not a fault. As if MSFT would ship something like MSIE without understanding how COM worked. The ignorance is laughable.

   I commented on Aarons blog. These are not JScript owned objects in some scenarios they can not be GC’d.

   Another point is the use of your script.

   When the page changes domain (or possibly just URL) the memory is freed anyway you are only accounting for people constantly refreshing and not navigating.

   Why bother?

   And another point is that I have made very big DHTML applications that leak pretty badly but they have been running for years without too much problem i.e. it’s generally not worth worrying about anyway. Who cares if IE is using 100megs of memory (and that’s worst case).

   Tim, as far as I know the memory isn’t cleaned while the browser is still open.

   Well it’s been a while but I’m quite sure it is cleared on change of url or domain. I’ll fire up an app @ work tomorrow and look.

   Erik Lippert made some reference to this somewhere.

   Not sure if you got my e-mail. Boodman sent me a mail saying that the memory is never cleared even after closing the window.

   MSFT released a patch that purported to fix the memory “leak” issue (i.e. circ. refs to non JScript owned objects) back in ~Aug 2002 and this produced the behaviour I am describing. Apparently it broke many pages and they retracted it. This explains the current problems.

   I haven’t worked with hardcore DHTML since end-2002 so I missed the MSFT patch retraction. My mistake was making the assumption IE6 would behave the same now.

   I have some quotes and shit to back this up will post on my blog tomorrow.
