Which problem? Process is run using C functions like execve. How vim runs system('command')? It runs execve("/bin/zsh", {"/bin/zsh", "-c", "(command) >/tmp/... 2&>1"}, env) (checked out with strace). You see: while one can call command directly it is calling shell and it calls the command. This has nothing to do with threading, it is more about efficiency (which is even worse then you imagine as some users prefer to use interactive versions of shell just to be able to use their aliases) and escaping (I was thinking about python subprocess-like first argument handling in system(): it takes lists as this argument and either escapes it (no other way on windows) for the program (not for the *shell*) or constructs execve call with this list transformed into array of strings).
