dynamic packfiles to append objects gc/refcount process punches page-sized holes in them for pages fully within the space of unwanted objects, after setting a tombstone mark holes are recorded in an index and re-used then, if desired, the repack process removes all the punched holes and anything surrounding from unwanted objects that are slightly out of the page boundary .idx is not a bsearch because that would cause me to need to rewrite the entire pack every time i add objects; instead use an extendible hash table. genreational bloom filters
