[tarantool-patches] [PATCH v2 0/2] SWIM log TTD, and suspicious anti-entropy

[Vladislav Shpilevoy <v.shpilevoy@tarantool.org>]

The patchset is logically bound to another mail thread "SWIM log TTD, and TTL".
It does the same with TTD, but solves the problem of resurrection in another
way, which does not depend on time. See message of the second commit for
explanations.

V1: https://www.freelists.org/post/tarantool-patches/PATCH-02-SWIM-big-cluster-improvements-part-1
Changes in V2:
- Drop commit about preference of new events over old ones;
- Move logarithmic TTD in a separate commit;
- Make anti-entropy suspicious in order to prevent member resurrections;

Branch: http://github.com/tarantool/tarantool/tree/gerold103/gh-4253-dissemination-speed-v2
Issue: https://github.com/tarantool/tarantool/issues/4253
