I thought I'd take a look at the epoll_reactor implementation.  I thinking of using asio proactor style code to use kernel bypass libraries.

I wanted to see how you do async IO with a pool of threads.

I think I see a bug.  None of the operations there done outside of the lock seem thread safe.  They unsafely modify linked lists.

    lock.unlock();
    read_op_queue_.complete_operations();
    write_op_queue_.complete_operations();
    except_op_queue_.complete_operations();
