[Boost-users] proposed modif for boost connection

I took a look at libsidc++ and found very interresting the way of
blocking/unblocking connections.

I added some small modifications in boost::signals lib in order to have this
functionality (2 patches in attachment to apply at the parent of the
boost_1_32_0 distrib). Only the interface of connection has changed (3 new
methods), and I added a boolean flag in basic_connection struct.

So, my questions are:
1) is it interresting to incorporate it (for me, YES, it is veru useful)?
2) is it a safe implementation?

You can test it like that:
  MySignal sig ;
  boost::signals::connection conn1 = sig.connect(&fct1) ;
  boost::signals::connection conn2 = sig.connect(&fct2) ;

  sig(10) ; // call fct1 and fct2

  conn1.block() ;
  sig(20) ; // call only fct2

  conn1.unblock() ;
  sig(30) ; // call fct1 and fct2
