Compiled C Extension Non-FFI Tools?

[metaskills]

To your knowledge is there another Ruby project that compiles a C extension vs using FFI? I've done some measurements with ruby-libvips which also uses FFI and I think I have witnessed a very very small performance loss when using FFI. So was just wondering if you knew of inotify alternatives?

Thanks in advance!

You can easily implement it yourself, you only need to replace lib/rb-inotify/native.rb
