In this context, I wonder what you meant in 2009, when you wrote:

| 	- redefines the "createNewClientSession()" member function to

| 		- otherwise increment the counter and create a new 

"just return" sounds a lot like "return NULL", but since that
createNewClientSession doesn't take any parameters by your claim above
it must not return NULL. Did you suggest to return something else?

Of course, 6 years is a lot of time and the context may have changed,
does the advise from 2009 still hold?
