<br>
thanks for the patch and sorry that it get lost on the first submission.<br>
<br>
The patch compiles fine and it doesn't seem to change interfaces a lot. <br>
So I would say it is OK. I'll give it two or three more days of review <br>
before pushing it.<br>
<br>
Please remind me again in a week in case I forget to push it.<br>
<br>
Best regards<br>
<br>
Christian<br>
