Management of large buffers incl. shared memory

---

The idea of this module is to count the shared memory allocations, and to provide information whether shared memory is well available or tight

This is now also used for large buffers that are not shared.

type id = [ `Buf_id of int | `Shm_id of int ] 

type kind = [ `Buf | `Shm ] 

type condition = [ `Normal | `Tight ] 

type watermarks = {

	low : int64;
	high : int64;
	max : int64;

}

exception Shm_max_exceeded

exception Buf_max_exceeded

class type shm_manager = object .. end

class null_shm_manager : unit -> shm_manager

class netplex_shm_manager : unit -> shm_manager

module Netplex_shm_manager: sig .. end
