One way to look at that is as an opportunity: if we fix the debug info bloat, that will surely speed up compile times (particularly -O0) even more.  As it turns out, Eric is working on this exact area (shrinking debug info for C++ apps).

Eric, can you talk about some of the things you've observed and your possible approaches to tackle this?
