I found another buggy place with huge exposure changes between spots that look about the same in mxl-school.

Did you mean MB? If a probe uses 6 * 32*32 * 3 bytes that's 18K so you could only store a handful of them with that much memory.

I don't think we should add the flag except where it is actually needed.

Normally you don't have to request linking to pthreads unless you directly use the pthread API, e.g. `pthread_create`. For example, with MinGW, you do need `-pthread` if you explicitly use...

Well if you want, you can test whether it builds with `-pthread`. Or if not, just toss in the flag on FreeBSD too to be safe.

Oops typo, I meant you can test whether it builds WITHOUT `-pthread`. FreeBSD is the same situation like Mac, if you base it on whether the pthread API is actually...

I guess this is probably obsolete but in case there's still anything to be tested, I now have a test suite...
