[issue47245] Subprocess with vfork() is broken

Rewriting in a way that guarantee no stack (and heap) usage. Because stack is shared between child and parent. It seems there is no crossplatform way. Happily we can use some code like I wrote by link in the first message. OR, stick to posix_nspawn which is cross-platform.
