Yes, I don't think that we will be able to avoid some refactoring of
the existing callbacks. The introduction of a new one may not be
completely necessary, though, especially if we reuse the reset
callback to be called when the stats read and write finish to close
any fds we may have opened when processing.
Maintaining the state of the files opened within each stat kind code
across multiple calls of the new "serialized" callback feels a bit
more natural and more flexible, at least it's my take on the matter.
