Michal,
Sorry for the slow response - my mail filters weren't behaving well at 
all...

For now, lets just drop this patch. I don't have the time to fix it up.
A few months ago I did take a look at what it would mean to use make's 
-j option
and it seemed to me that doing so would require completely changing how 
the coccinelle
script works.

I would like to see my M= patch set merged though:

Thanks,
Greg
