example

When only thr1 was enabled thr2 was commented out:<br>
tstsrv:/home/aaron # ./collect_files_threaded.pl -u aaron | wc -l
3948

When only thr2 was enabled thr1 was commented out:
tstsrv:/home/aaron  # ./collect_files_threaded.pl -u aaron | wc -l
1436

When both were enabled (below code):
tstsrv:/home/aaron  # ./collect_files_threaded.pl -u aaron | wc -l
1753

Each thread updates a global variable.

I got the code generated by find2perl command to create the function findFiles.
