I did some more testing. This time with network.ping-timeout set to 2 seconds. The results are the same. A reset (killall -KILL glusterfsd) on the "bad" brick will bring the disk io down on the machine and ultimately require a re-initialization of kvm+libgfapi. 2 seconds is well inside the normal tollerance for the root filesystem, so it must be some other type of problem. Perhaps libgfapi returns an error when it should not ? I am sure that this is not intended behavior for gluster and libgfapi: it defeats the whole purpose of having a replicated cluster and running kvm on top of that. Any comments are welcome.
