CppNix did this here: https://github.com/NixOS/nix/pull/13708

Is it safe? I think so since our evaluator is not concurrent, but I am not 100% sure.

cl/3880

should be safe, boehm stops all threads except the scanners via signals. this does fuck with our already fucky signal handling though and we do not want this merged without a) stress testing, and b) gdb scripts that make this less of a fuck to deal with when debugging
