   Faster the second time.

   With 8 GB the OS apparently is busy in the background and takes 4x as   
   long, a linear increase.

   If we go back to 1 GB the memory/diskspace is apparently pooled.

   The timing suggests that the pool is increased, not build from 0.

   The WorkingSetSize reflects the program's size + allocated memory.   
   AFAIR, this was a lot worse a few years ago.   
   Mysteriously, available memory size is still 16 GB.
