Thanks again for taking the time to read this!

require 'feed_library'

# my callback for the live feed
FEED_CALLBACK = DL.callback('0PL') { |result_list, count| }
  if result_list
    record = FeedRecord.new(result_list)
    puts record.code
  end
}

# handle used to request for a feed
handle = FeedLibrary::log_on("user", "password")

session = get_live_feed(handle, FEED_CALLBACK)

# my attempt to keep this running and waiting on the callback:
while true

end

Here's one I tried. Been playing around with different approaches. With 
this method I noticed I always get the cross-thread violation when I use 
the FeedRecord structure. If I don't use the structure and do something 
else like using the struct! method I'm able to get away with the 
callback being performed a couple of times then it eventually leads to a 
cross-thread violation.
