In addition to that, you can share the whole thing ("tmp") for projects 
that use the same local.conf and the same OE version. Building various 
images for about 20 different machines with over 4 different 
architectures (MIPS and ARM variants) in the same directory works just 
fine and drastically reduces build times since they can share about 
everything that's not unique to each machine.
