No, I'm referring to the threading model assumed when, for instance,
building a test with

  test-suite "foo" : [ run foo.cpp ] ;

So, threading=single is assumed here, right? That poses a
small problem, as on the other hand BOOST_HAS_THREADS and
BOOST_HAS_PTHREADS seem to be unconditionally defined, which
can lead to Pthreads being used by foo.cpp, but not linked
by bjam.
