I examined the code yesterday using a directory with 50000 files (empty  
files, but
that should not matter). The X11 file selector spent more than 45 minutes  
to open
that directory. I gave up after that. I have investigated the code and  
there
were a few things that certainly did not scale. Loads in 1.7 seconds after  
the
fix. That fix will be in 11.1

I also made a small test program that called stat(2) and gettimeofday(2)  
for each file.
It spent approx. 0.1 seconds going through all of them. So that is not a  
problem.
