...graceful degradation. Simply adding a blank line invalidates all the following source locations. My plan is to ignore any profile data whenever the source changes in any way. We had some discussions about this, and it is easy to come up with cases where even a trivial change to the source, e.g., enabling a debugging flag, causes massive changes in the profile data. I don't think graceful degradation should even be a goal. It is too hard to sort out insignificant changes from those that should invalidate all the profile data. I am still at least a few weeks away from having any details to sh...
