+Things that still need to be done: -*- Text -*-
+
+ o - Performance
+
+   All performance could be tuned, but one area that could be looked
+   at especially is performance with flags, particularly
+   --detect-odr-violations and --compress-debug-sections.
+
+ o - Threads
+
+   Why is the usertime when we run with threads the same (or almost
+   the same) as when we run without?  Is it because threads spend most
+   of their time waiting on the same resources?  On each other?
+   Something else?
+
+ o - ODR false positives
+
+   ODR false positives can happen when we optimize, since code in .h
+   files may be optimized in different ways in different compilation
+   units.  It's possible we could fix this for real by looking at the
+   full debug info and using DW_TAG_inlined_subroutine in a clever way
+   to correct for inlining.  But that would be very expensive, I
+   think.  The easier solution is to recommend people only do
+   ODR-detection with -g0.
+
+ o - Better testing
