Yes Ubit. This may well produce a "unspecified result", at least 
unrecoverable by script. Definitely not something one should rely on.

This may be the explanation. Client-side and server-side movements 
are hard to reconcile. I tried llTargetOmega for a crane, starting 
and stopping it at precise angles with timers, and it was ugly. 
llSetKeyframeMotion may do better since we can catch the moving_end 
event.

BTW, here is your script in action :
