hm, did not find it there. but 100usec seems very far fetched. Even with
posix realtime extension. I assume you want something like:
do smthg
wait x microsecs
do smthg
problem is: wait x microsecs never waits x microsecs but almost always more.
even with realtime priority / -signals / whatever.
that's at least my experience. If I am wrong please correct me.
