I was wondering, does this same problem also apply to dictionaries? From what I can tell from a quick look inside `write_array_data`, buffers are truncated to any sliced portion but it seems to me that unreferenced dictionary values might still be written (e.g. consider if the dictionary was passed through `filter` such that only a few keys exist, it looks to me that the values will be passed unchanged through the filter kernel). I wonder if there's a possible need for a `.gc()` method on dictionaries which does similar to in the view arrays? -- This is an automated message from the Apache Git Service.
