It's not as easy as it seems, as "being online" may differ
depending on what interfaces that are enabled. For example,
AmiTCP and MiamiDx allows you to be connected to several
nets at once, so you can't tell if you're online, you can
only see if you can reach a specific host.
I open bsdsocket.library only on demand, and tries to connect.
If it doesn't work, I'm not online, or something else might
be interfering (my ISP goes bust, a router bursts into flames,
etc etc)
