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. 

It it necessary to have queue as a global variable? As this peace of code is so sensitive it is better if we give to a queue a name more meaningful than "queue" in order to avoid looking at it in a couple of months wandering what "queue" is used for :-D
