Description

I have been working on https://github.com/xedin/disruptor_thrift_server and consider it as stable and performant enough for integration with Cassandra.

Proposed replacement can work in both on/off Heap modes (depending if JNA is available) and doesn't blindly reallocate things, which allows to resolve CASSANDRA-4265 as "Won't Fix".
