That's a good question to be asking, and the answer is NO, you
cannot exhaust memory that way. Constant string literals such as
"Circle" are guaranteed to exist for the life of the program

(I would need to check the exact wording to figure out
if they still exist while processing a routine registed
via atexit() )
