--------------------------------------------------------------------
You can find an new version of the patch :
- without hamcrest dependency
- compute the generation of expireTime into gossiper and calling it into the
constructor of VV
- modify SS to be more readable
- adding some log
I hope it's ok :-)

> Currently dead states are held until aVeryLongTime, 3 days. The problem is
> that if a node reboots within this period, it begins a new 3 days and will
> repopulate the ring with the dead state. While mostly harmless, perpetuating
> the state forever is at least wasting a small amount of bandwidth. Instead,
> we can expire states based on a ttl, which will require that the cluster be
> loosely time synced; within the quarantine period of 60s.
