Read the MAX_WORKERS value in /etc/default/<proxyname>. If it is not
an integer between 0 and 128, ignore and warn.
The lower limit was chosen because at least one worker process must
exist. The upper limit was chosen because more than 127 worker
processes should not be necessary and a positive impact on performance
is doubtful. If this limit turns out to be too low, it can still be
extended in the future.
