Yes, quite strange. It's fixed in IE9 (at least my test no longer
fails) so clearly considered a bug.

To your original point, Boris, if there's no way to reclaim the memory
for a pre-fetched script _until_ its executed, then even legitimate
use-cases (e.g. pre-fetching auto-completion data) by "responsible"
authors would be of concern.
Would a means by which authors can mark a pre-fetched script as
"stale" allay some of your concerns? Is there some way to accomplish
this in Gecko now for a pre-fetched Image?
