But how to run a binary without forking first? I would have to be
`exec getppid`.

Procfs is nice but lives in a word of cats, echos, ls -l – I mean,
it's a world of text, files and symlinks. IMO it is good to allow
users cat etc. it from interactive command line, but for short
programs, it's like taking away coherency from them, they have to open
a channel for this file tree, I feel this is unstable.
