Very few tools presently use the redblack API.  It's one of those golden nuggets that should be used more, but we haven't done well to take advantage of it.  At a glance, the tools currently using it are just g_lint, remapid, and pixcount.

I believe those were fixed, but need a quick testing.

That was a report from a user, unconfirmed.  Needs someone to see if they can reproduce the crash.

Bonafide bug in the TIE rendering code.  Probably something simple, but it needs debugging.

That's not strange at all, just a bug in new optimization code that cropped up during release testing.  It's probably an off-by-one or similar issue in "THE NEW WAY" code in src/librt/primitives/bot/bot.c.
