Popen.wait(timeout) is currently implemented on Unix-like systems using a busy wait, since the waitpid system call doesn't have a timeout argument.

On Linux, it's now possible to do better than that. You can create a PID file descriptor using pidfd_create and poll that descriptor with the specified timeout. Popen.wait should make use of that.
