SUMMARY

Can the thumbnail process be made less CPU intensive? And also thumbnail only
what is in the current view?

STEPS TO REPRODUCE
1. Fill up a folder with 26k 300 DPI color A4 pnm pictures.
2. Add this folder to digikam

OBSERVED RESULT

3. Digikam becomes mostly unresponsive, trying to make thumbnails.

EXPECTED RESULT

"Digikam should not eat too much at a time." Maybe put a configurable sleep or
CPU cap on the thumbnailing process.
