[nitpick] The loop variable name was changed from for _, flushed_segment to for flushed_segment, but the dictionary key is no longer being unpacked. This is a minor inconsistency - consider keeping the unpacking pattern for shard, flushed_segment to maintain clarity about what the dictionary keys represent, especially since shard information is now important in this multiprocess context.

The isinstance check is redundant here since the kill() method exists on threading.Thread as well (it's just not typically used). However, the more important issue is that this code only kills multiprocessing.Process instances but not Thread instances, which could leave threads running. Consider handling both types or document why threads don't need to be terminated.

[nitpick] The shards parameter is now passed to the main() method but the corresponding function signature at line 137 shows it's the second parameter. This creates a coupling where the order of arguments in the tuple must exactly match the function signature. Consider using keyword arguments or documenting this dependency more clearly.
