[Boost-users] BGL and threaded graph modification

Hi! I am wondering if it is possible to modify a single graph object by multiple threads which attach edges into seperated regions of the graph? To be exact: I have a set of vertices in my graph with index 0-maxIndex which I want to copy a couple of times into that same graph structure one after another. Of course, I assure that there are no resize events during copying and no overlapping. This should be possible, I think, at least in theory, but I found no word about that in the docs of the BGL. So, should it work or not? Thanks, Sebastian
