Has this really been tested? I played a little bit with it and it was
very painful when whole distribution will be rebuilt due to a minor
change in an early package.

There are some subtle bugs in the hash generation too (e.g. bitbake's
get_file_depends() result is used to calculate a hash over a set() which
is filled nondeterministically when BB_NUMBER_THREADS>1) which cause
random rebuilds too.
