I'll be preparing a patch for our posix_spawn's signal handling. My mistake in my setuid assessment was pointed out to me- it doesn't seem like a highly likely attack vector, but it is indeed possible. If the child errored out, they will indeed be properly reapable at that point due to how vfork is implemented -- any observation to the contrary is to be considered a bug.
