I don't see any unnecessary reloading here:


Ok, modules loaded: [snip].

Tried this on both x86_64/Linux (Fedora 6) and x86/Linux (RedHat 7).  Any 
idea what might be different about your setup?

That module did take about 15 seconds to load up in GHCi.  It looks like it 
  contains quite a few datatypes and a lot of derived instances (derived 
using TH), so my guess is it's just large.  Does it take significantly 
longer to compile with 6.8.1, or has it always been slow?
