Drb question

ruby-talk

i never really seem to do more that play with drb and then forget everything,
nonetheless this perplexes me:

   ~ > cat a.rb
   require 'drb/drb'
   mode = ARGV.shift || 'server'

   case mode
     when 'server'
       a = ['foobar']
       DRb.start_service nil, a
       uri = DRb.uri
       puts "ruby #{ $0 } client #{ DRb.uri }"
       DRb.thread.join
     when 'client'
       uri = ARGV.shift
       DRb.start_service nil, nil
       a = DRbObject.new nil, uri
       p a.size
       p a.unshift
   end

   ~ > ruby a.rb server
   ruby a.rb client druby://fortytwo.merseine.nu:1241

   ~ > ruby a.rb client druby://fortytwo.merseine.nu:1241
   1
   ["foobar"]

   ~ > ruby a.rb client druby://fortytwo.merseine.nu:1241
   1
   ["foobar"]

it appears that unshift returns the entire array in this case? what it this?
slap me if this is a stupid question.

thanks.
