As promissed, here is an update on the cpu usage, more than a week after 
applying the fix (in .htaccess):

 ---------------------------------------------
           |  For the week  | For the day    |
           |  rank  -  %    |  rank  -  %    |
 --------------------------------------------|
 cpu       | 337th - 0.059% | 697th - 0.021% |
 hit       | 708th - 0.021% | 857th - 0.016% |
 Bandwidth | 692th - 0.024% | 840th - 0.017% |
 ---------------------------------------------


So, Drupal is still using much more CPU than other applications hosted at the 
same place, but the discrepancy between cpu and hit/bandwidth is not as bad 
as when I was spammed for trackbacks.
