Comment (by ncohen):

 Hmmmmmm... This is still very long `:-/`

 {{{
 sage: g = graphs.RandomBipartite(7,7,0.7)
 sage: %time g.line_graph().is_perfect()
 CPU times: user 104.32 s, sys: 0.07 s, total: 104.39 s
 Wall time: 104.86 s
 True
 }}}

 Could you make the graph smaller, or at the very list add a "# long time"
 flag to those two lines ?

 By the way, perhaps it could make sense now to add some code in
 `is_perfect` to check if the graph is the line graph of a bipartite
 graph... As we can now compute the root graph `:-P` I wonder what the
 performances would be `:-)`
