I can't get a straight forward answer on this. Is Google's V8 engine really limited to 1 VM per process?
If google's v8 engine is limited to only 1 VM per process, then doesn't it sort of exclude itself from being used in libraries? Say I code up a c++ library that uses V8 called LibA. And someone else codes up another library that uses V8 called LibB. If an application links to both LibA and LibB bad stuff would happen (right?).
I need a fast (with speed being the most important requirement actually) javascript parser for a lib I'm trying to write, but I don't want to use v8 if I'll run into this problem (it's likely that the kind of applications that link to it will also use v8 at some point).

The V8 engine uses the Ignition interpreter, which takes in the Abstract Syntax Tree as the input and gives the byte code as the output, which further proceeds to the execution phase. When the code is being interpreted, the compiler tries to talk with the interpreter to optimize the code.
V8 is Google's JavaScript engine, written in C++. It compiles and executes JavaScript code inside of a VM (Virtual Machine). When a webpage loaded into Google Chrome demonstrates some sort of dynamic effect, like automatically updating a list or news feed, you are seeing JavaScript, compiled by V8, at work.
V8 JavaScript engine was initially developed for Google Chrome and Chromium web browsers to improve the performance of JavaScript execution. The project's creator, Lars Bak, created the first version that was released at the same time as the first version of Google Chrome in September 2008.
V8 is Google's open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors.
Based on this closed bug report, it's safe to say that Google's V8 engine is not limited to a single thread per process (since approximately April 2011).
