Good point -- I often put a try-except for EnvironmentError
around things to catch errors resulting from external conditions
and report them to the user. So I'd prefer something that didn't
descend from EnvironmentError for this.

TypeError might even be more appropriate than ValueError, since
a non-blocking socket could be considered the wrong type of
object to do buffered I/O on.
