 Replying to [comment:37 rzen]:
 > The patch attached to #26239 is a clean and lightweight solution to the
 issue at hand. I'm certainly not opposed to a more robust rewrite — there
 are many benefits to be gained no doubt — but it would be great if we
 could fix the issue first, then iterate and improve from there.

 Just like all the other solutions that make a copy of the array,
 http://core.trac.wordpress.org/attachment/ticket/26239/26239.patch is not
 backwards compatible. You can't modify callbacks for a filter while it is
 running.
