I am finilizing work on Boost unit test library that is supposed to 
have required feature and hopefully be able to present it soon. You 
can look into the CVS for current state of the libary (Beman/Ullrich 
version; tag unit_test_development) and give me your opinion what do 
you expected see. Anyway I will think about adopting of Khuth 
algorithm. And I also would also be interesting in the reference.
