the timestamp thing was something i popped in since it seemd (to me,
at least) a good way to get rather unique "cookies" for each query.  i
doubt very much (but would be delighted if someone could
authoritatively comment either positively or negatively about this)
that two calls to gettimeofday(2) could ever return the same struct
timeval.

to take the cookie thing a little further, have your identd simply
hand out a strictly increasing value (0, then 1, then 2, etc), keep
track of what it handed out last, and what each number maps to (either
via logging or some other simple method).

my point was only that they be unique.
