Sorry if I'm spamming too much.  Just to be clear, I agree completely with your sentiment but I'm pretty sure that `__clear_and_shrink()` has exactly the same effects as `clear(); shrink_to_fit();`.  Maybe `reserve(0);` should should be unconditionally calling `__set_long_cap(0);` immediately after deallocating?  I could be missing something obvious though.
