Title: Make automatic log flushing configurable

As discussed in GH #4277 this allows to configure, wether the application log should always be flushed (for debugging) or only as the OS sees fit (for performance).

Currently it defauts to no autoflushing in production and enables it everywhere else.

This needs some minor editing to apply against HEAD because of commit 55cc16f.
