 No, you don't need to make the serialization with
 marshal_load/marshal_dump, here an example

vgs% cat b.rb
#!/usr/bin/ruby
require 'socket'

class A
   def initialize
      @a = UDPSocket.new
      @b = {1 => 2}
      @c = [3, 4]
   end

   def marshal_dump
      [@b, @c]
   end

   def marshal_load(x)
      @a = UDPSocket.new
      @b, @c = x
   end
end

p Marshal.load(Marshal.dump(A.new))
vgs%


vgs% ./b.rb
#<A:0xb7ca06cc @c=[3, 4], @b={1=>2}, @a=#<UDPSocket:0xb7ca0668>>
vgs%
