Parallel

This is a revolution.

Behold your eyes as I unveil the new wonder of this age.

Parrallelized PSUL.

Waiting for seven hours is so passé, level up you apps with the power of parralelization !

with 6 threads, I was able to make a daily run of PSUL in 24 minutes. 

The optimal number of threads should be 8, assuming nothing else runs. 

Maybe I am annoying but can you document somewhere that Queue is a thread-safe implementation of a queue?
