New description:
The following test from sage/graphs/generic_graph_pyx.pyx takes a very
long time:
{{{
TESTS:
Running the algorithm on random instances, just to make sure the
answers are still satisfiable path (the algorithm would raise an
exception otherwise)::
sage: for i in range(200):
... g = graphs.RandomGNP(20,.1)
... _ = fh(G,find_path=True)
}}}
At the very least, it should be marked {{{# long time}}} but even then I
think it takes way too long.
Also, it looks like {{{g}}} should be {{{G}}}.
