Does Sage have a general framework for providing progress updates during its computations? More generally, a system for logging and reporting messages of various sorts, apart from tracebacks triggered by uncaught exceptions?
I ask because I recently "found" Python's logging module: http://docs.python.org/library/logging.html It seems to be extensive, but I have no experience with it, particularly its effects on performance. But with the right level of granularity, good top-level design and Sage-wide logging policy, and lots of help from contributors, perhaps the Logger class is a good base for [optionally] recording a history of a calculation. This might be useful, for example, for following the branches of a non-deterministic algorithm, comparing how Sage arrives at an answer on different platforms, or simply having a rough answer to "What is Sage spending so much time on now?" Sometimes, the source code itself offers too much detail, at least initially. Just as there is a dedicated "div" for introspection in each notebook cell, how about a similar logging div that's hidden by default. Of course, a user should be able to select among levels of detail.
