Multithreaded?

I was wondering, is libraw multithreaded when calling unpack()?
I would like to be able to use all cores on the tablet I am developing for, and am wondering if there is something to do about the speed on those limited devices?

Forums: 

unpack() is not multithreaded

unpack() is not multithreaded because
1) it is not possible for Lossless JPEG format (Canon CR2 and so), you need to read input byte-to-byte
2) for simple formatts (e.g. Fuji RAWs) the code is disk limited already.

Postprocessing steps are partially multithreaded via OpenMP
