Yes, I think that it remains a concern. But I'm sure that improvements can be made while keeping it in mind.

1. We'll need to ensure that the data is allocated contiguously in linked binary, so that touching it doesn't dirty more pages than necessary.

2. Ideally, this static allocation will be done in a way that doesn't immediately make the memory dirty. If it's done this way, touching e.g. one EventName could dirty more pages than necessary.

(1) is could cause a memory use regression from what we have now. (2) can not be a regression, it's an improvement opportunity. Ordering EventNames by how common they are could save some memory.
