New description:

 Before May 2010, we resolved bridge IP addresses to country codes in the
 sanitizing process and appended them to the nickname, e.g., UnnamedDE.
 This was possible, because we sanitized descriptors in batches which was a
 semi-automatic process.

 When we switched to sanitizing descriptors automatically, we took country
 codes out, because the code was too complex and broke all the time.  The
 difficulties were that descriptors can arrive in any order (while we still
 need to come up with the same set of sanitized descriptors) and that we
 need to update the GeoIP database periodically.  That's not impossible to
 solve, but also not easy to get right.

 We should find a way to make this work, maybe by relaxing the requirement
 to update the GeoIP database at all.  The old code that we took out in May
 2010 is
