Process! is not propagating Beaneater::NotConnected exception.

[b-sridhar]

As mentioned in the title, the process! method does not propagate or break from the while loop when there is Beaneater::NotConnected exception i.e when the Beanstalkd goes down.

Steps to reproduce:

1. Start beanstalk: beanstalkd -l 192.168.50.21 -p 11300 &
2. Put messages to the queue.
3. Start the consumer.

   @beanstalk = Beaneater.new('192.168.50.21:11300')
   begin
   @beanstalk.jobs.register('my-tube') do |job|
     puts "Job: #{job.inspect}"
   end
   @beanstalk.jobs.process!({:reserve_timeout => 10})
   rescue Exception => e
   puts "Exception: #{e.inspect}"
   @beanstalk.close
   end

4. Stop the beanstalk server.
5. The consumer is now hung as the process! method keeps retrying considering Beaneater::NotConnected as a StandardError.
