Hi Vincent,
I'll take a look early this week. There's clearly a bug; the SpurGC 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.
So Vincent's awful sats are no longer showing up? He reported a 140 second GC pause. What are you seeing? (.i.e. can you post the full stats?) If this has disappeared then I suspect my Slang bug, which I fixed yesterday. But I will investigate.

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.
