I am relaxed, especially after I had a good laugh reading this:

   On a less related note, I hope you will agree that the simpler
   mechanism for this very in-demand feature is long overdue on Linux
   (every man and his dog are passing fds around these days).

Really, in years and years of unix programming, I have not yet felt
the need to pass a file descriptor. Thats goes double for my dogs.

In any case, I find it hard to believe that the traditional method is
really so bad. The explanation of why this new way is needed boils
down to: "unix programming is so hard to get right."

Thanks,
Richard
