These are interesting ideas, but I'd rather have a deep dive on
profiling the current Elisp.

If an agenda cache is required, it can be very simple. Associate entries
to agenda files. Whenever a file is modified, drop all the entries. No
need to refresh it IMO. I doubt many agenda files are modified between
two agenda calls.
