Problem:

SSCSM is still not implemented, after years.

Suggestion / plan:

First, implement a SSCSM that has just client-provided (checksumed, to avoid cheating) builtin (SSCSMCPB).

Desour

Goal: Reduce release delay and uncertainty.

Reasons I saw why releases get delayed:

* the milestone doesn't get empty
  * there's some regression(s). and a bugfix is not in sight
  * someone wants a 90% complete feature in the next release
* coredevs inactive. (no active work being done to get progress in the remaining
  issues)

Desour

general remarks:
* a shape is a bitmap where bit i is 0 iff slot i is ""
* all recipes get a number at registration, this number is an index into an array.
  higher number was registered later => can be used for priority
* caching should also be added later

// copied and adapted from the example in man page futex(2) ("futex_demo.c")

// requires libfmt (because of personal dislike of c++ stream output)
// compile with:
// g++ -O2 -Wall -Wextra -std=c++17 -g -o "test_futex" "test_futex.cpp" -lfmt

// The busy waiting uses x86-64 intrinsics:
// * rdtsc: IIRC, the timestamp values are processor-specific. (No longer used,
//   benchmark runs faster without it.)
// * pause: always available on x86-64

The Problem

LuaJIT does not compile creating closures (see http://wiki.luajit.org/NYI#bytecode). However, sometimes we do want to create closures at runtime and pass them as callback parameters.

Example:

	-- load time
	local function maybe_call_callback(f)

Desour

local n = 1000

minetest.register_chatcommand("swi", {
	params = "",
	description = "",
	privs = {},
	func = function(name, param)
		local player = minetest.get_player_by_name(name)
		local item = player:get_wielded_item()
