	In my world, "sleep" is a blocking operation -- the process is blocked
from execution until the sleep expires or is otherwise canceled.

	So a socket.select() with timeout is a blocking operation -- just that
it is released when any of the multiple items (read sockets, write sockets,
timeout) is satisfied.
