Maybe what I saw is only an artifact from debugging and tracing (which
also inserts into buffers...)

I'm totally unsure what is going on.  Is there anything I could try to
turn off?

A CPU profiler report looks like this, with stuff less than 3% removed:

       24220  41% - timer-event-handler
       21654  37%  - timer-activate
       19231  33%   - timer--activate
       17774  30%      timer--time-less-p
       19949  34% - ...
       19949  34%    Automatic GC
       14040  24% + command-execute  ;; actual command execution time
            [...] [...]

This is a very strange result, not saying anything to me.
