Thanks,  Thiago. 

In that case, I guess I need ond copy of the graph per thread.  Correct?

And since we are at it,  does anybody have experience in using graph-tool wrapped inside Cython code? 

Cheers, 
Pedro

This is not implemented, but can be achieved easily with threads or
multiprocessing.

I don't think this is true, since the library dispatches to C++.
