You should be fine. I believe there are locks (mutex) around places where this is known to be a problem. I’ve never heard user reports of issues in this regard.

I'm noticing on the website it says "OGR layers: use unsafe CPL services"...In my map file I have 'CONNECTIONTYPE OGR'....what I do with the map object is project, and then draw to png, and that's about it....this isn't thread safe then? What about if I have multiple map objects, one per thread....is that thread safe?
