-# * include management of a persistent nodemap in the main docket

-#      - for censoring operation
-#      - for stripping operation
-#      - for rollback operation
-# * proper streaming (race free) of the docket file
-# * track garbage data to evemtually allow rewriting -existing- sidedata.
-# * Exchange-wise, we will also need to do something more efficient than
-#   keeping references to the affected revlogs, especially memory-wise when
-#   rewriting sidedata.
-# * introduce a proper solution to reduce the number of filelog related files.
-# * use caching for reading sidedata (similar to what we do for data).
-# * no longer set offset=0 if sidedata_size=0 (simplify cutoff computation).
-# * Improvement to consider
-#   - avoid compression header in chunk using the default compression?
-#   - forbid "inline" compression mode entirely?
-#   - split the data offset and flag field (the 2 bytes save are mostly trouble)
-#   - keep track of uncompressed -chunk- size (to preallocate memory better)
-#   - keep track of chain base or size (probably not that useful anymore)
