Library Nomination Request - Concurrent Wrapper

Hi

I would like to nominate my library under 'Asynchronous Event Loop' section. It is called [Concurrent Wrapper](https://github.com/gimesketvirtadieni/conwrap) and it implements 'multiple providers / single consumer' pattern. I made an extensive description so kindly ask to let me know if you could include it into your awesome list ;)
