I found yet another, uhm, let's say "tweak" that results in a speed-up. 
  /usr/bin/startkde (this script is used also for KDM logins) sets 
MALLOC_CHECK_=3.  Argh!?  No wonder I had crashes with programs that 
were previously working.  And the system seemed so much slower.

I deleted the offending lines from startkde and restarted KDE.  The 
machine seems to be back to about the same performance as with KDE 4.6 
now.  I can't imagine what a negative impression this will leave on 
people trying 4.7 RC1 :-/
