like I said, "peter´s right, no reallocation in operator*.".
I should have differentiated between get(), reset() and operator* in that 
description.
the fact is that only reset() needs to reallocate, and the discussion of 
possibly changing the implementation of thread_specific_ptr should be 
continued on that basis, no matter what I mistakenly wrote before.
sorry for the confusion.
