[Tarantool-patches] [PATCH 0/2] Fiber storage leak

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

The patchset makes fiber.storage be always deleted. Regardless of
where was it created - in a fiber born in the Lua land, or in a
fiber serving IProto requests and accessing Lua.

That removes

  - a leak occurred each time when fiber storage was created for
    an IProto request;

  - a possibility to see previous request's artifacts left in
    fiber.storage;

And makes possible to use fiber.storage as request-local data.
