This sounds like good idea, modulo the pesimization of
code in main. I am not sure how important it is except
for trivial benchmarks.

BTW I believee that the current aligna code keeps stack missaligned and alignes
the returned poitner.  I will check.

Yup...
I am going to track the confusion soon, once I hit the
missoptimizations reported, that are more serious
and I am receiving bugreports (especially because of
profiling) few times a day.

Hope it is tracked down by the 5 patches waiting in
queue now.
