 Sorry, I don't have the time right now to make the tests, but I will try
 to look at them this WE. I go quickly through your patch, and I'm not sure
 of all the changes you made. I will try to look carefully this WE too.

 Do you have any other changes in the pipe for SFTP client ? So I don't
 take too much time to change something already changed :).

 Thanks for your help.
