Hello,

Since David seems to be away for this week before seeing my mail asking 
for an ack from him, now this can only get in by Philippe or Peter. (David 
said before he'd be OK with the series if Philippe acked it so I think 
that can count as an implicit ack and it could always be reverted before 
the releease.)

Philippe, do you have anything against this to get merged now? If not 
please send a pull or ack it so it has a chance to be in 6.0 or tell if 
you still intend to do anything about it before the freeze. This series 
was on the list since January and the remaining parts you did not take are 
here since February 22nd and the version after your first review since two 
weeks so it would be nice to sort this out and not block it any further 
without a good reason.
