Indexing hammers even a good CPU

On a Framework 13, with a six-core AMD Zen chip, the indexing process, on its first run, took some five minutes, which is fine, and pushed the CPU to some eighty (80) degrees, which is not. No background task should use so many resources (without explicit permission). That the Framework has loud fans worsens matters but is not Recoll's fault. (The inbuilt fan profile for the machine is dire. I've overridden that with something saner, but any sane fan profile is going to run the fans hard at 80 degrees.)

Admittedly, a subsequent indexing run hit only some 57 degrees [EDIT: a later pass briefly hit 70-something] and, admittedly, the first indexing was not, I suppose, quite a _background task. Nevertheless it seems to me that the index should use, or be configurable to use, less of the CPU.
