I wonder now if one could emulate fork-shenanigans-exec by:

- clone CLONE_FILES with AF_UNIX socketpair

- send file descriptors through the socket

- do whatever was in shenanigans (you have the socket for communication/RPC/whatever)

- exec

or maybe even easier:

- clone CLONE_FILES with pipe or two

- do whatever was in shenanigans (you have the pipe for communication/RPC/whatever)

- exec
