Hi Florian,

I am collecting here your comments for the model we are defining for
set elements:

https://people.netfilter.org/pablo/setelems-timeout.txt

Let me know if you have more possible scenarios that you think that
might not be address by this model:

- Annotate current time at the beginning of the transaction, use it
  in _expired() check (=> timeout is not a moving target anymore).
- Annotate element timeout update in transaction, update timeout from
  _commit() path not to refresh it.

Thanks.
