Hard to get much better than vfork+exec in terms of performance.. but
implementing vfork+exec has it's hairy parts and is why posix_spawn is
better even if it ends up being just vfork+exec.

additionally performance isn't really a big issue here, avoiding the
swap usage explosion is the main reason why touching any of this.
