This is fixed in the 0.9 release, which will be coming out
"any day now".  I used a simpler hash than Digest::SHA1, but
your suggestion of Digest::SHA1 will make me go back and
consider using that instead.

Voiceglue almost certainly doesn't need the cryptographically sound
MD5 solution with its associated CPU cost.

The issue of collisions is a valid one, though.  My guess is that
collisions will probably never happen, but I'm still pondering a
multi-entry-bucket structure just in case they do.
