Yesterday it was not swapping yet.  I'm monitoring memory usage with
gkrellm.  When it starts blinking red, which was the case yesterday,
memory starts running out.  It skipped the blinking yellow state, which
means that a lot of memory must have been acquired in a short time
period.

I regularly use some Helm commands (e.g. for C-x C-f or M-x) but not
helm-mode.

I think we see different symptoms.  I don't see any slow-down at all
(unless swapping starts, obviously).  When I do M-x garbage-collect, it
finishes immediately without freeing an significant amount of memory.

I was not using this command.

Maybe our problems have a similar cause, but seems they are a bit
different.
