But, as you pointed out, closed?() is not the same as eof?().

Watching for an IOError also isn't very reliable since HighLine's  
input stream may be anything from STDIN, to a Socket, with IO and  
StringIO in between.

For now, I've added a workaround so user code can disable HighLine's  
EOF checks as needed.

Thank to all for helping me to understand this issue.
