Yes, sorry. There are some nasty dependencies among them.

* Tests for 'Allow the use of a not-conflicting protocol value inside a 
   subchain'

depends on:

Mon Sep 16 20:50:06 CEST 2013  Gian Piero Carrubba <gpiero at rm-rf.it>
   * Fix test suite
   Modify expected results in order for the tests to pass after applying the 'Sort
   hash keys when iterating' patch.

   * Tests for 'Conditionally enable the inherited protocol in a subchain'

While

* Allow the use of a not-conflicting protocol value inside a subchain

depends on:

Wed Sep 18 19:16:51 CEST 2013  Gian Piero Carrubba <gpiero at rm-rf.it>
   * Conditionally enable the inherited protocol in a subchain

Please also note that the numbering of the patches was in reverse order 
(my fault).

If you already have an idea about which patches could be acceptable and 
which are not, I can try to rebase them accordly.

Ciao,
Gian Piero.
