Could I use that to avoid the problem if I do this:

  Thread.new(request) { |request| ... }

This is a big problem since the "request" into the block points to the request 
outside, so each thread share it (dangerous). This is why I use:

  Thread.new(request) { |req| ... }

Could I use this?
  Thread.new(request) { |;request| ... }


Thanks.
