I understand your background ideas here however the non-deterministic
lock release is driving us crazy at the autobuilder management. The
sstate cleanup script, workdir cleanup script and in-house scripts all
need to be teach to deal with this and this is far from optimal.

Would be acceptable for you a command line option to 'wait' it to
release the lock before exit? This could be done easily and we avoid
side effects. This also provide a solution which is isolated enough to
be safely backported for previous releases and provide more
deterministic script output.

How does it sounds?
