Dot making no progress.

Hi there,

We have a graph (yes I know it is large) that is not too much bigger
than other graphs we render relatively painlessly. I have tried limiting
all the things I can find to limit but alas dot appears to spin.

DotIssues iam$ dot -v -Ln3 dotIn.xdot -Txdot -o dotOut.xdot

It sits at this last line for as long as I have the patience to wait
(currently a couple of hours). We are not that fussy about the layout,
but we are addicted to xdot output, because we use it to draw our graphs
in an interactive java environment, in particular the nodes and edges.

Any suggestions? (other than me checking out the GitHub repo and seeing
what has got its knickers in a knot). I cannot attach the graph as per usual,

(the web form says: The selected file dotIn.txt could not be uploaded. The file is 702.06 KB which would exceed your disk quota of 1 MB.)

so I have put it here:
