# Bitbake can generate an event showing which setscene tasks are 'stale',
# i.e. which ones will be rerun. These are ones where a stamp file is present but
# it is stable (e.g. taskhash doesn't match). With that list we can go through
# the manifests for matching tasks and "uninstall" those manifests now. We do
# this now rather than mid build since the distribution of files between sstate
# objects may have changed, new tasks may run first and if those new tasks overlap
# with the stale tasks, we'd see overlapping files messages and failures. Thankfully
# removing these files is fast.
