So, your python script does not write the pdf, just invokes some 
other commands to do the job, and waits for completion?
In this case, I doubt Python would be a bottleneck, so the easy way 
is to launch a new process on each job.
If you get many requests per second and notice that it's the Python 
startup which is slowing down the whole process, then you could 
consider changing it.
But in that case I'd change the way the PDF are converted, not the 
Python script which controls that.
