[gdal-dev] Multithreaded GDAL

Hi all
I've tried searching for an answer online, but the most recent information I found is more than 3 years old.
We have method that reads pixels from one data-source, performs some manipulation, and writes it to another.
Reading is done with the Band.ReadRaster C# API.
Writing is done with the Band.WriteRaster c# API.

I'd like to process several data-sets in parallel on multiple threads.
>From what I could understand from http://trac.osgeo.org/gdal/wiki/FAQMiscellaneous and other online sources, "no threads can be writing to GDAL while others are reading".
Has this changed in recent versions? Is it now possible to read and write on different threads (from different data-sets)?

Thanks
Yehiyam
