    nb: SocketPoll class to poll events on N-Sockets
    
    Internally SocketPoll manages the sockets
    and handles the polling and firing of callback.
    
    It's thread-safe and handles asynchronous calls
    to remove sockets correctly while potentially
    being in poll(2).
    
    The choice for using poll(2) compared to epoll
    or select are the following:
    
    1. For our use-case, poll(2) works great up to
       a few hundred sockets, which we don't expect
       to have on a single document normally.
    
    2. select(2) has an awkward API (modifies input,
       f.e) and has limit on max fds that we need to
       be mindful of (even if we'll not hit it in
       practice). poll(2) preserves the input and has
       a no-nonsense API that's simple and readable.
    
    3. While select(2) is the most portable, poll(2)
       isn't far behind. Yet in practice we'll probably
       not support other systems than Linux.
    
    4. epoll(2) starts to scale with hundreds or
       thousands of sockets. Meanwhile, it has high
       overhead to adding/removing sockets (context
       switch to kernel and back). Our typical case
       will have a handful to a dozen sockets.
       Hardly a justification for epoll's heavy guns.

    nb: bind reuses address automatically
    
    This is virtually always desirable, since
    without it we may fail to bind after recycling
    if the previous socket is TIME_WAIT.
    
    However, if a socket is bound to same address
    this will not prevent the failure to bind,
    and we'll detect that the address/port is busy.
    
    So the advantage is in minimizing recycling time.
