This seems like the sort of thing that should already exist. I want a profiler that displays the source code to the program, coloured according to how often the code was executed during the test run -- so it's easy to spot the paths in the code which need to execute rapidly, because they'll all have "bright" colours. The same sort of approach could be used for general execution path visualisation, or for displaying test coverage.
