Mathias, mind to re-check if this behaviour persists with latest SVN
(v2.3.x and/or trunk) and I-pipe 1.7-02? If yes, please file a short bug
report to

https://gna.org/bugs/?group=3Dxenomai

so that it doesn't get lost (we plan to manage non-trivial bug-tracking
increasingly via that channel).

I consider this a non-critical issue. Still, it has to be understood and
probably fixed.

Jan
