Actually the unlock/lock get's called every time (I've broke the if statement there!).
I thought about using a count hook - but just unlocking and then locking again seemd
much more simple, since with a hook I need an alarm to set the hook if the current 
thread has had its share of time. 

The situation I'am worried about with unlock/lock (inside main interpreter loop) 
is a case where thread A running lua with state L1 gets preempted by thread B wich 
calls a lua script with state L1 (same state).

I've had a closer look at hooks and now I see it is the safest way.
