It took a night's sleep for this to fully sink in, but I get it now.  A class 
that allocates memory would normally have a destructor that frees the memory. 
But only one instance of this class is created per process, so there's no need 
for the destructor.

I'll send a patch with a comment in case you think it might be helpful to future 
readers of the code.
