[Tarantool-patches] [PATCH v2 00/16] Transaction engine for memtx engine

[Vladislav Shpilevoy]

A lot of new expenses come from struct txn becoming huge.
It could be mitigated if you would introduce a new object
which would store struct txn, psn, all the new rlists. And
which would be created only when needed. However it may be
wrong if you will enable the new manager by default with
keeping on_yield error.

I sent some comments, but I didn't review the patchset whole
yet, it is huge.
