shared-state avoid dependence from clock
shared-state avoid dependence from clock

Use a Changes To Live counter instead of a timestamp to decide when an
  entry should expire, the good part is that we don't depend on clock,
  the bad part is that it is not trivial to extimate how much an entry
  will stay in the shared state, as it depends on how often the state
  changes.
