The following illustrates the problem on OS X (and I believe linux)

accumulator = []
first = true

10.times do |i|
   a = []
   a << "!" * 10000000

   #a[0] = nil

   a.shift

   accumulator << a

   GC.start
   stdout = `ps v -p #{ Process.pid }`
   stdout = stdout.split(%r/\n/)
   printf("\n         %s\n", stdout.first) if first
   printf("%6d:: %s\n", i, stdout.last)

   first = false
end
