... actually, I'm not sure how useful it is - it requires initializing the symbol handler with `SymInitialize` and point to a path to find the symbols. Plus that the symbol handler is single threaded and any calls to that would need to be guarded with a global mutex. So I think I'd defer that for now at least.
