Below you will find a list of ongoing projects to improve the quality of Sage:
- performance regression/timeit for doctests - #3476
- pickle jar - see #3482
- Patch Review Committee
- caching memory limit to prevent Sage gobbling up all system memory
- turn caching on/off - maybe even by subsystem for error checking/performance regression
- fine grained optional doctests, i.e. "Stein's Axiom I: Everything not tested is broken"
- remove all "nodoctest" from the Sage library tree and fix failing doctests
- more and better documentation of process, i.e. bundles vs. patches, patch bombs, best practices
