We implemented USDT probes on Linux in cl/2884. We can support dtrace on macOS, in theory.

It appears that there's not an Apple (tm) dtrace package in nixpkgs yet, so that needs fixing as a preliminary action. It looks to be in the Apple SDK lock file in nixpkgs, so it exists, but AFAICT there is no packaging.

That tool is just required to generate the .o and .h files to do the probes. ~~I am about to file a nixpkgs packaging request and shove it in the external issue tracker please hold.~~

Update: no it DOES exist, see darwin.dtrace in nixpkgs. So then we just have to do some minimal packaging in Lix.
