Increased memory usage with GHC 7.10.1

Actually, I never allowed GHC to completely run out of memory. I just killed the build process 
when it consumed all of physical RAM memory and started growing into swap. At that point machine 
becomes barely usable and the build practically stalls as CPU usage drops to 0. FYI: both 
machines have size of swap equal to size of RAM.
