True on Unix-derived systems, where 'select' includes the various 
derivatives.  It is also an abstraction over the Windows completion 
calls, which are quite different.  The latter is why one must generally 
use a different event loop on Windows.  The point is that asyncio 
provides an *abstraction* such that after choosing the event loop, the 
rest of one's code is os-agnostic.
