Is a my problem of initialization of Scheme object or a Kawa bug? 

I do some strange errors too.  I guess there is some thread contention
someplace, but I don't know where it might hiding.

I've seen you are currently working on Kawa servlet. Should not this problem make also the Kawa servlet implementation fails? All servlet containers works with thread pools, if two requests for a new page (I still don't know if the problem is in parsing/compiling/evaluation) come at the same time, the container would execute Kawa as in the posted example. Have you ever tried a stress test of Kawa servlet (e.g. with 'JMeter' or 'ab')?
