Comment:

 Yeah, so we want something smaller, we don't need the 20 second variant.
 We can probably just cut Reid's test case in half or even a third and
 check that in, double checking the behavior is still fixed (which is
 obviously pretty easy). I'll get on it shortly.

 I'm also moving this to 7.10.2 - the `tidyOccName` fix already applies
 cleanly in my tree.  The evil simplifier bug applies modulo a small change
 in `SimplCore` - so this is an excellent bugfix to go in!
