 * Here we have an abstract pointcut that is used within a cflow.  In the two concrete sub-aspects
 * we make the abstract pointcut concrete.  The aim of the test is to ensure we do not share
 * the cflow counter objects, since the pointcut within the cflow() in each case points at a 
 * different 'entry' point.  The count should be 10 when we finish.  If it is 8 we have shared
 * a counter.
