Hi Vincent,
I'll take a look early this week. There's clearly a bug; the Spur
GC is /not/ collecting those dictionaries :-( (thanks Stephan!).
I'm afraid the dictionaries are part of the model and should not be
garbage collected. They do make things slow though, so we need a better
model. Garbage collection cycle takes a few seconds now on my 4 GHz 4790K
32GB. Stephan

I sent you the stats by mail, they were only posted to the moose mailing
list. I'm afraid my somewhat better results can only be explained
through faster hardware, a 4790K i7 on 4GHz, running Ubuntu 15.10.
Loading the mse file still spends 2/3 of time in garbage collection, at
least mostly. I had one run that was much better 85s -> 66s, I thought
by not creating so much garbage.
