In another couple of releases, posix_spawn(2) will also hopefully

I've been curious, what are the advantages to using posix_spawn(2)
instead of fork(2) + execve(2)?
posix_spawn(2) provides the performance benefit of vfork(2) +
execve(2) while still allowing you to manipulate attributes of the
child process that could not safely be done with vfork(2). And it's
arguably a cleaner API for process creation (though that's more a
matter of style).
