FWIW, I was having similar problems and a good blast of compressed air 
to my CPU heat sink fixed the problem. I ran 'dmesg -w' while building 
and it was pretty obvious that my CPU was overheating because I got a 
lot of messages like:

[ 3657.188178] mce: [Hardware Error]: Machine check events logged
[ 3957.206279] CPU2: Core temperature above threshold, cpu clock 
throttled (total events = 1005969)

I wonder if there are some changes in Morty that make it better utilize 
the CPU compared to the other releases?
