Description (last modified by bill)

removeChild leak protection needed in 0.9 dojo core or base. Refs #1727

let's just port the (simple) destroyNode code and not worry about deferred removal cases like removeNode.

then need fix all references in dijit to call destroyNode() rather than parentNode.removeChild() (look for PORT comments)

Component: DOMHTML

Talked to Alex about this; he thought using this.outerHTML is dangerous. But apparently there's a memory leak issue, right? The alternative clearing this.outerHTML is to put the node in a dummy "garbage can" bin and then clear that bin's innerHTML.

The garbage can came from the drip/sieve site. And that is how I proposed it in the .4 days. I think Cougar was having problems with this across iframes/documents. Each document would need to have it's own garbage can and clear it. The outerHTML was proposed at that time to workaround the multiple document issue.

Note: we talked with Alex about this about a month ago; we agreed he'd add a semi-public_destroyNode() method that we could call and then we would test it and see if it made things better/worse.
