mem-isolate
https://github.com/brannondorsey/mem-isolate
Purpose
mem-isolate allows you to run potentially unsafe or memory-leaking code safely by isolating it in a separate process.
Core Mechanism
Uses the POSIX fork() system call to create a child process that executes a user-supplied function in isolation.
Guarantee
Ensures memory purity--changes in the child process do not affect the parent process.
How It Works
- Creates a
pipe()for communication. - Calls
fork()to spawn a child process. - Executes the function in the child.
- Sends the result back to the parent via the pipe.
- Parent waits for the child to finish and returns the result.
