Would you mind giving me really quick and brief overview of the implementation or point me to the code please ?

The Project Loom update from JVMLS 2019 [1] might be useful. About 7mins 
in, we used ServerSocket::accept as an example and you'll see the code 
path (in the form of a stack trace) to see how the yielding when there 
are no connections to accept. We follow that with the unpark/continue 
when a connection is ready to be accepted.
