- Update async procedures to use explicit raises annotation - Modify TrackedFutures to handle futures with no raised exceptions - Replace `asyncSpawn` with explicit future tracking - Update test suites to use `unittest2` - Standardize error handling across network and async components - Remove deprecated error handling patterns This commit introduces a more robust approach to async error handling and future management, improving type safety and reducing potential runtime errors.
