nginx timeouts

[FlominatorTM]

Since my webhoster relocated my scripts on a new server there are some configuration problems. The biggest is that user receives nginx timeouts if the query is too long or ends in an endless loop (see #20)

The reason for this new behavior is that as opposed to earlier the page content is not written directly to the browser but seems to be buffered.

In the process of this migration php was upgraded from 5.x to 7.x which I also performed on my development environment. There it also didn't flush anymore.

After applying some of the tips from https://www.jeffgeerling.com/blog/2016/streaming-php-disabling-output-buffering-php-apache-nginx-and-varnish to the code it works on development environment again, but unfortunately still not in production. I'm still working with the webhoster to figure this out.
