-- Implement proper operation handles that allow users to wait for specific events
-- Clean up the read operation for clients
-- Check that the corner case where read and writes go over the length of the file work correctly
-- Return the number of bytes read or written in the ToastyFS_Result struct
-- Make parallel uploads/downloads configurable
-- Recalculate next write locations whenever a write occurs, not at each read
-- avoid replay attacks
-- find a way to remove over-replicated chunks and formalize the chunk management policy
-- add logging of:
-    - when chunk servers connect and disconnect to the metadata server
-- Should list scenarios that need testing, like those where chunks would be dropped
-- Update DESIGN.txt and the code to remove the chunk list message. The information of chunks
-  held by chunk servers is now transmitted to the metadata server during state updates
-- clean up the replication factor business
