Accelerated ExecJS Runtime by launching Node.js Processes per Context, not per execution.
inspired by execjs-fastnode
The existing Node.js runtime spawns a Node.js process for each eval, regardless of whether it compiles or not. To reduce this overhead, execjs-fastnode is designed to launch a single Node.js process and manage the Context in JavaScript.

execjs-fastnode is designed to limit the number of threads that can access a Node.js process to 1 to avoid the race condition when multiple Contexts are used. execjs-pcruntime works lock-free by creating a Node.js process for each Context. This improves performance when used with multi-threading.
