It feels solved - many thanks!
Still I have two questions:
a) how large is the cache size (it seems that
   around 3-4 Raws are kept in memory)?
   Could/should one make this configurable?
b) When being in preview mode (with loading of the full image
   marked as active), there is something which puzzles me:
   Using PageDown for the sequence  
     IMG_8305.CR2  
     IMG_8306.CR2
     IMG_7061.CR2  
   I get the following  dcraw commands
   shown on the konsole :
   - Still in thumbnail view (i.e. initial start): 
     kdcraw -c -v -4 -h -H 0 -b 1 -w -q 0 -o 1 IMG_8305.CR2
   - then preview:
     kdcraw -c -v    -h -H 0 -b 1 -w -q 0 -o 1 IMG_8305.CR2
     kdcraw -c -v    -h -H 0 -b 1 -w -q 0 -o 1 IMG_8306.CR2
       (i.e preloading works!)
   - then PageDown
     kdcraw -c -v    -h -H 0 -b 1 -w -q 0 -o 1 IMG_7061.CR2
     kdcraw -c -v -4 -h -H 0 -b 1 -w -q 0 -o 1 IMG_8306.CR2

     Question: what is the -4 variant being used for ?

   Such a command sometimes also gets triggered for images, which apparantly
   are still in cache (at least the display is instantaneous)?
