I'm not sure I understand this question, but to the extent that I do
understand it, I think you might think something that isn't true.

There is no "the pool" as far as that empty string is concerned. It's
not allocated in a pool. Troy just meant that some other pool might be
cleared or destroyed, and that this wouldn't affect the statically
allocated (and probably shared) empty string.
