It would appear that such tests are required to execute completely 
inside of a function block.  Unfortunately, the very nature of a 
singleton makes this impossible.  I need to be able to check the 
lifetimes of singletons with relation to each other, and with relation 
to static and global objects.  This means I cannot even use cout to 
report results, as the standard streams could close up shop before the 
last of my singletons is destroyed.

At the moment I am thinking that I will need to write two test 
programs... one to test the singletons and generate an output file, and 
one to verify the contents of the file that was generated.  Does anyone 
see a simpler way?

Also, I should ask what the policy is on testing classes that use a 
policy based design.  How many different combinations of policies are 
expected to be tested?
