Short answer - no. The test framework is reentrant, but not thread safe. 
This is a conscious decision. At the moment I do not know the best API to 
use for critical section guarding. Your best bet would be to wrap Boost.Test 
tools with your own that does invoke guards. Also you could make sure 
somehow that all test tools invoked from single thread. Or... you could 
present solution that would incorporate fix into test framework.
