deny(unsafe_op_in_unsafe_fn) in libstd/process.rs
The libstd/process.rs part of #73904 . Wraps the two calls to an unsafe fn Initializer::nop() in an unsafe block.
Will have to wait for #73909 to be merged, because of the feature in the libstd/lib.rs
As a relative beginner, it took a while for me to figure out I could just steal the references to avoid partially moving the child and thus retain ability to call functions on it (and store it in structs etc).
