4579 (restarting Chandler hangs for 1-2 seconds between module imports): Tracked the actual cause of the problem to a problem with twisted (4376), that BrianKirsch patched. There are still noticeable dynamic linking issues on the Mac, especially on slower machines; I'll be looking at these further this week.
4275 (minical rendering performance): Change reviewed and checked in. Green boxes in tinderbox performance output observed.
Plan
Spend a day on 4118/4119 (Event creation performance)
Continue work on 3052/4579 (Mac linker performance)
Other 0.6 performance work, as well as bug fixes and documentation.
