More elaborate examples include being able to provide services to the children that interact with the parent process state (e.g. linux /proc filesystem, based on Plan 9 concepts). This is how it works. The parent process creates an fd, and mounts that into the current filesystem view (...
Currently, on Linux, Runtime.exec() uses fork() or vfork(), with vfork() being the default. This is controlled by -Djdk.lang.Process.launchMechanism, with allowed values of "FORK" and "VFORK" on linux. Enable the use of posix_spawn() on Linux as it is used already on Solaris, ...
