Started really looking at the results from Coldshot and realized that the line timings just didn't add up to the function timings... because the line-timings were "localtime" rather than "cumtime".  Local time is actually pretty interesting as a piece of information, but I'm guessing 95% of the time you actually want cumtime when you are looking at a function at the line-profiling level. Will have to add it next week.  Only other major piece missing is the func:func relative time mappings (and function's localtime from that).  Both are loader-side calculations.
