Yes, that is exactly what I mean: reentrant member functions and no static data which can be
damaged by parallel execution of multiple context instances...

My intention is:
I have a lot of source files, which I would like to preprocess by some number of threads. Each
thread will own a dedicated context instance and preprocess the source file. Will this work, of do
you for example have some static tables or whatever, which would be written by this contexts at
the same time?
