Slowdown

[andygill]

There are reports from EECS 776 that blank canvas slows down after playing a blank canvas game for a bit (~30 seconds). We need to figure out if that is a blank canvas issue, or an idiom issue.

Do we have any additional information with these reports? Are the slowdowns temporary or perpetual? Is this compiled or interpreted? I have had some temporary performance losses while using ghci, but I think the timing was generally random.
