Here's a new version, I think I addressed all of the feedback I got,
although may have missed something.
Hopefully it is easier to test with sthen@'s fix.
Thanks miod@, espie@, sthen@, and especially gkoehler@ for a lot of
excellent feedback.
I'm sure there's still stuff missing and obvious problems that don't
stand out to someone who writes a lot of perl.
Starting Saturday I'm traveling for work for the week, so will probably
be even less responsive than usual until I'm back.
