This information is taken from the hash map populated during

Result "None" - means installing/removing of our packages is not
currently in progress. However, it doesn't mean that any other yum
instance is not running at the same time, but we ok with this
because our yum process will start processing automatically once
standard /var/run/yum.pid lock is removed by other process
