leakless

Run sub-process and make sure to kill it when the parent process exits. The way how it works is to output a standalone executable file to guard the subprocess and check parent TCP connection with a UUID. So that it works consistently on Linux, Mac, and Windows.

If you don't trust the executable, you can build it yourself from the source code by running go generate at the root of this repo, then use the replace to use your own module. Usually, it won't be a concern, all the executables are committed by this Github Action, the Action will print the hash of the commit, you can compare it with the repo.

Not using the PID is because after a process exits, a newly created process may have the same PID.
