The eventfd system calls can allow us to implement some Linux-specific high performance version of some event notifier abstractions in the standard library. 

eventfd() creates an "eventfd object" that can be used as an event wait/notify mechanism by user-space applications. The object contains an
unsigned 64-bit integer counter that is maintained by the kernel. This acts as a file descriptor that can be used by the usual suspects (read/write/poll/close...).

The advantage here is that the kernel maintains the counter and if used in conjunction with poll/epoll, it allows for a high-performance and
scallabe event notification system.
