Comment (by akaariai):
Ok, now there is a get_language safe patch for this.
The performance statistics are as follows, using
http://localhost:8000/test/10000?timing:
With this patch, 1,5 seconds on average
* get_language calls (10000) use about 0.3 seconds of this.
* smart_str in start of get_format uses 0.15 seconds.
* the new caching mechanism uses about 0.1 seconds of this.
Without this patch, about 9 seconds on average.
With USE_L10N=False, about 0.7 seconds.
I haven't yet ran the tests, will do that tomorrow.
