Perhaps I'm not understanding it correctly, but as I see the
entries are marked as expired/reclaimed by special values (0/-1)
in tv_sec/tv_usec. Then, the netstat display should show either
the same integral or the same fractional part for all affected
time differences since the base time is the same for all.
It doesn't...

Btw, I think that it would be better to use microuptime(9)
rather than microtime(9) for these interval things, to make
it robust against time changes. Or getmicrouptime(9) to save
some cycles - accuracy shouldn't be an issue.

best regards
Matthias
