Create decorators module in view/helper and add view decorator that catches exceptions like DeadlineExceededError, MemoryError, AssertionError (this code is being moved from respond function). Add view decorator to all view functions. In addition remove not needed imports from all affected files and fix too long lines.

templates: search list of templates (or just a single template not in a
