to many hdd reads

[Stefan Groschupf]

Hi,
don't think I'm fuddy-duddy but is it really sensefull to do following 
in the nutchbean?

File [] directories = fs.listFiles(indexesDir);
     for(int i = 0; i < fs.listFiles(indexesDir).length; i++) {

wouldn't it be better to do it like this:
File [] directories = fs.listFiles(indexesDir);
     for(int i = 0; i < directories.length; i++) {

First of all that are many unneccesary disck reads and second there is 
theoretically a chance that the numbers of files change until the loop 
and this will throw an exception.

Should I provide a patch or someone of the contributor just change this 
one word?

Thanks!
Stefan
