I had actually tracked this one down, since our servers had encountered
this.  The root-cause problem was that the CLIENT field is 16 chars
long, but hostnames were limited to 64 bytes, but checked against the 16
char CLIENT field.  If your hostname was longer than 16 chars it looked
like a new one, and was inserted as a new row in the CLIENT_STATISTICS
data structure; a new row was added for each connection.

CLIENT was 16 chars because it shared the same data structure as
USER_STATISTICS.  The reasonable fix seemed to be to either make a
different structure that had CLIENT as 64 bytes, or to truncate host
names to 16 characters to match the stored value.
