run/runAsync without blocking jvm shutdown

[maxandersen]

currently ProcessBuilder blocks jvm shutdown if processes have not finished at jvm shutdown:

///usr/bin/env jbang "$0" "$@" ; exit $?
//JAVA 21+
//DEPS io.smallrye.common:smallrye-common-process:2.20.0

import static io.smallrye.common.process.ProcessBuilder.*;
public class SmallRyeProcessShutdown {
    public static void main(String[] args) {
        var seconds = args.length == 0 ? 3 : Integer.parseInt(args[0]);
        newBuilder("sleep", Integer.toString(seconds))
                .whileRunning(process -> System.out.println("child pid: " + process.pid()))
                .runAsync();

        System.out.println("main() returning immediately; child sleeps for " + seconds + "s");
    }
}

any reason why?

forces me to use other API's to kick off background jobs.

Thats sad :)
