This change introduces a `-W /dev/pts/1` flag to redbean. What it does is use the mincore() system call to create a dual-screen terminal display that lets you troubleshoot the virtual address space. This is useful since page faults are an important thing to consider when using a forking web server. Now we have a colorful visualization of which pages are going to fault and which ones are resident in memory. The memory monitor, if enabled, spawns as a thread that just outputs ANSI codes to the second terminal in a loop. In order to make this happen using the new clone() polyfill, stdio is now thread safe. This change also introduces some new demo pages to redbean. It also polishes the demos we already have, to look a bit nicer and more presentable for the upcoming release, with better explanations too. |

DESCRIPTION
Lua is a language designed for embedded use in native applications. It
has an impossibly elegant C API and the Lua language itself feels more
like Python compared to alternatives like Tcl except it's a great deal
faster and doesn't have strong opinions about character encoding.
PROVENANCE
https://github.com/lua/lua/
commit e7803f7dbcdc966ab1f9db143424ee811ab1a398
Author: Roberto Ierusalimschy <roberto@inf.puc-rio.br>
Date: Wed Mar 3 09:44:20 2021 -0300
New release number (5.4.3)
luac.c needed to be sourced from:
https://www.lua.org/ftp/lua-5.4.3.tar.gz
LOCAL MODIFICATIONS
Lua now uses a bestline REPL with bash-style code completion.
Integer literals such as `033` will now be interpreted as octal.
Integer literals such as `0b10` will now be interpreted as binary.
The `\e` string literal escape sequence has been added, which is
equivalent to `\27` (the Lua version of `\033`) or the ASCII ESC
character. It may be used for teletypewriter control like having
bold text, which can be encoded elegantly as `\e[1mHELLO\e[0m`.
Added luaL_traceback2() for function parameters in traceback.
Added Python-like printf modulus operator for strings.
