class WEBrick::Utils::TimeoutHandler
Class
used to manage timeout handlers across multiple threads.

handlers should be managed by using the class methods which are synchronized.
id = TimeoutHandler.register(10, Timeout::Error) begin sleep 20 puts 'foo' ensure TimeoutHandler.cancel(id) end
will raise Timeout::Error
id = TimeoutHandler.register(10, Timeout::Error) begin sleep 5 puts 'foo' ensure TimeoutHandler.cancel(id) end
will print 'foo'
