I can't recall accurately but maybe it was std::make_shared() that was 
missing? And yeah I absolutely needed std::async, std::promise, 
std::thread, and std::filesystem. I didn't want to reimplement them myself.

Give me praise for resisting the temptation of coroutines that requires 
C++20! Some part of my code is a bit messy because of the lack of 
coroutines but if I took the path people would throw stones at me in anger!

Yup, actually I developed it on NetBSD 9 with pkgsrc GCC 8 so it surely 
works on older systems where GCC 8 is available.
