I had the privilege to work with Gilles on a paper for the first (and
only?) xenomai users meeting in Dresden in 2009.  Our topic was the
fast context switch extension (FCSE) for armv5 machines.  Gilles made
the FCSE actually work and creatively expanded the idea in a useful
way.  I was able to meet him in person in Dresden on that occasion,
and I will remember him as a true gentleman with a good sense of
humor.

We are thankful for Gilles' many contributions and remember his
kindness to those wanting to learn more about real time systems.

Rest in Peace!
