Sorry for that. I'm still getting used to the thing called 'git'. Apart
from obviously sharing its name, there's not so
much we have in common so far... VCS experiences currently
don't go far beyond svn and the horrid CVS.
I just used the reply-list from the initial series about this subject,
perhaps you were listed twice in that one as well.

Isn't no longer making --chain-reply-to the default an option?

That pretty much looks like what I need at first sight. I'll definately
give it a very close look and test it out.
The perf_event approach would be nice, but the implementations
just seem to collide.

Thanks for taking the time anyway,
Stijn
