Sorry about the typo, etcshadow!

I glanced through the perl58delta, but did not see any architectural changes to memory allocation. Could there be something else causing the slowdown?

At this point, I've become interested in this issue above and beyond just solving my particular sequence-reading problem. Is this a bug or a feature of perl 5.8...?
