Such phenomenal work. BTW, for anyone on a Windows machine, getting this to work is very trivial. There is a unix only library for locking files (fcntl) which prevents it from working on Windows. I mocked it in the path and made a function that returns 0 to test it. Obviously adding a check for os and switching to a cross platform file locker would be a great contribution. I'll see if I can make that happen in the next week.
