I'm saying that from my experience in working with GEOS code, C++ API only. I don't see any multi-threading/thread-safety techniques provided in GEOS code. There is no mutual exclusion, no indirection in raw pointer usage, no guarantee of atomic operations in access to global/static data, no usage of thread synchronization techniques, etc. This tells me there is no thread-safety in GEOS. Certainly, I may be wrong and there may be something I've not learned, so I'm interested in deeper discussion too.
