Indeed, that makes no sense. The only thing that comes to mind is that
when they do `M-x garbage-collect` the 15 minutes aren't actually spent
in the GC but in some pre/post command hook or something like that
(e.g. in `execute-extended-command--shorter`)?
Do we have a `profiler-report` available for those 15 minutes?
I've taken a quick look at the massive threads in that bug report,
but haven't had the time to read in detail. AFAICT we don't have a
profiler output for those 15minutes, so it would be good to try:
M-x profiler-start RET RET
M-x garbage-collect RET ;; This should presumably take several minutes
M-x profiler-report RET
and then shows us this report (using C-u RET on the top-level elements
to unfold them).
