Unfortunately the Emacs that was 8GB has since been stopped, I killed
it before working with the trace files. My laptop was rebooted later
when the trace statistics utils ate all the RAM (my error, wrong input
file).

This list of timers is from a new instance, but the configuration
hasn't changed.

Are the 50+GB of trace files I have of any value?
