problem with parallelism feature example in documentation

Vladimir,

I'm pretty sure you added the <parallelism> feature example after a 
similar question from me;-) Only now I start to really understand the 
power of this and how to do it. So I tried it but bjam tells me that I 
have a recursivity problem and have no idea why.

I isolated the problem in a small test-case. Attached are the project 
sources (3 files with each one function), my user-config.jam and the 
error message.

Thanks for any help in advance.
