No, I'm just saying that it does not make the existing fork/exec
path slower. We don't have full solid benchmark results yet, but overall
it looks like:
- fork/exec performance does not degrade
- posix_spawn performance is very similar to vfork/exec (which is not too
I prefer a clean posix_spawn over a vfork hack any time. Where not possible
(see mouse's mail), we can stick with vfork - it won't go away.
