I don't have any own benchmarks on that, but at least I had no
trouble with OpenMP in GraphicsMagick under C, C++, Python and
Ruby.

However, when I built a native Java extension under Linux,
any internal exception of my extension lead to a segmentation
fault, even if it was caught within the extension, so the
Java runtime didn't ever see it. That seemed to be some conflict
between OpenJDK's thread handling and that of GOMP. This
was really hard to debug and the only solution was disabling
OpenMP in GraphicsMagick. But I don't know whether it was the
fault of GraphicsMagick, GOMP or OpenJDK.

Feel free to play with that. :-)
