Matthew Flatt f1f4959b66 Chez Scheme: separate allocation and thread mutexes 
Instead of one big lock, have one big lock and one small lock for just
manipulating allocation state. This separation better reflects the
locking needs of parallel collection, where the main collecting thread
holds the one big lock, and helper threads need to take a different
lock while changing allocation state.

This commit also includes changes to cooperate better with LLVM's
thread sanitizer. It doesn't work for parallel collection, but it
seems to work otherwise and helped expose a missing lock and a
questionable use of a global variable.

README.md

Racket is a general-purpose programming language and an ecosystem for language-oriented programming.

This repository holds the source code for the core of Racket plus some related packages. The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization.

Quick Start

Pre-built versions of Racket for a variety of operating systems and architectures, as well as convenient source distributions are available at

https://download.racket-lang.org

Racket comes with extensive documentation, including several tutorials. You can read all of this documentation, as well as documentation for third-party packages at

https://docs.racket-lang.org

Building from Source
