[Boost-testing] Random test.sh failures with parallel multi-file test

Hi,

When I run test.sh on a busy SMP machine, I get occasional failures  
like this that I don't see if the machine has less load.  From what I  
can tell when the load gets close to 50% or more, I start to see  
failures in this one test.
