This version is slightly faster and much better on CPU time. My version wrecks the CPU. The only thing I need to do here is tweak this version to run with the same output as mine. I'll post the portion that actually runs the commands soon. I think something like this may make this tool run much better. Here is your code running with 1000 as max on the 7k+ servers: 

real    0m56.481s
user    0m2.515s
sys     0m2.165s

Using my default fork value as max of 100: 

real    1m26.502s
user    0m2.537s
sys     0m2.270s
