I just got mail from the Chief Privacy Officer of doubleclick.net
with a correction for a bug in the script.  I asked him for permission
to include his mail on the site.

value = value[:-1] is not needed.  I was throwing away the last
character of the cookie, not a newline character.

Assuming that the cookie is a true hex number (which it is) and one copy
can get duplicates of everything except the last character (which it
can) then 16 copies ought to be able to get complete duplicates.  

"distributed" version over the weekend, je pense.
