For those interested, here are a few latency measurements made with this
new patch on the various platforms I have, in order to compare Xenomai
2.6.1 with the current state of the upcoming 3.x branch.
The graphs show clearly that Xenomai 3.x has better average and minimum
latencies on low end platforms. The lower end the platform, the more the
latency graph is shifted to the left.
