I did, and as I said, the speed-up is impressive. What's also impressive is that 
can apparently detect if a rebuild is required because of a change in a 
headerfile no matter how indirectly that file is included.

The size of the ccache cache directory becomes impressive too - fortunately it 
compresses well (almost 3x even with the lz4 compression in ZFS).
