Look at http://www.geocrawler.com/archives/3/242/2001/10/0/6957668/ for some 
benchmark results. According to those, -z combreloc and prelink together 
reduces relocation time to 1% of the time without any (obj)prelink. I'm 
trying to verify this, but according to those statistics, -z combreloc alone 
should reduce the relocation time by 90%, and my tests only showed a 
reduction by 25% (measuring linking times of qt designer). OTOH, I only 
recompiled qt with -z combreloc, no other library (Maybe I'll try with a -z 
combreloc linked glibc if I'm in the dare-devil mood.
Something else that my tests showed was a significant increase in relocation 
time if I compile qt with gcc 3.x compared to 2.95, not depending on whether 
I used combreloc or not. I want do to the tests again bcause I'm not quite 
sure that I did all 4 combinations (gcc 2.95/3.x each with and without -z 
combreloc) right. That's why I don't present my results here.
