Networking HLAPI ClientRPC is received in reverse order

Just discovered that it seems RPCs which are buffered are dispatched in reverse order. This code on a network behavior which is spawned as part of the player object system:

Code (csharp):

1.  
2. void Start()
3. {
4.     if( NetworkServer.active )
5.     {
6.         for( int i = 0; i < 20; i++ )
7.         {
8.                 RpcTest( i );
9.         }
10.     }
11. }
12.  
13. [ClientRpc( channel = Channels.DefaultReliable )]
14. public void RpcTest( int index )
15. {
16.     Debug.Log( index );
17. }
18.  

Logs the following output to the console:

Expected output should be in order from 0 to 19, as "Reliable" should guarantee message order.
Seems messages are buffered and then dispatched LIFO, when they should be dispatched FIFO instead.
