The strings remember in which file they were created/assigned. However, this used a non-counting reference to a ProFile, which could become dangling. If a subsequent ProFile re-used the exact same address, a string's source would be mis-identified, which would be fatal in conjunction with discard_from(). Since we actually need only a unique id for comparison, let's use an integer for that.
