is this library nonblocking?

[ilovemysillybanana]

I have list of several thousand machines I need to ping(all on my company network so nothing shady!). Anyway, to speed this up I was trying to run 50 threads in parallel that would ping these nodes but it appears to me that this gem is traversing over itself when I do that.

Here is an example of how I am doing that:

data_queue= queue.new()
consumer = Array.new(50).each do |num|
  Thread.new do
    unless if queue.empty?
       temp = queue.shift
       data_queue << [temp, Net::Ping::TCP.new(Temp, 'http')]
    end
  end
end
consumer.each(&:join)

data_hash = Array.new()
loop do
  break if data_queue.empty?
  temp = data_queue.shift
  data_hash.merge!(temp[0] => temp[1])
end

Anyway, I'm giving it a list of 5000 machines but am only getting 50 unless I'm just confused as to how memory works in threading I think it has to do with this library not being thread safe.
