Thanks for this enjoyable link, Jude!

     Looks like the destination of the message is GKH : "I trust you 
because, in fact, I expect you won't insist to merge crap." :-) If GKH 
decided to merge crap, he would leave immediately the list of trusted 
submaintainers.

     Some new IPC tools have been introduced in the Linux kernel these 
years and I know some people disaprove this trend. But, at least the 
ones I know of are rather good in my opinion because they move IPC 
towards the I/O system: signalfd and eventfd. If kdbus ends up merged in 
the kernel, I expect it'll be properly amended to be a useful 
general-purpose messaging facility. Nothing we should be afraid of.
