Run the build below normal priority.

Browse Source 
The build compiles on every processor for ten minutes and more while the
job screen invites the player to keep using the PC. build.Run now starts
make_game.py with Windows' below-normal priority class, which the
compilers and the other processes the build starts take over from it, so
the build gives way to what the player does and loses nothing on an idle
PC.
