Previous releases did not have synchronized access to configfs in rtslib. This made it possible for rtstool or rtslib to attempt access to an element that had just been removed mid-loop by another Block Storage request (and was, therefore, non-existent). This, in turn, could result in any of the following exceptions: - .dump() - KeyError - IOError - RTSLibError on storage_object This release implements synchronized access to all rtstool calls that access or modify configfs. With this, concurrent access from multiple threads and processes now work consistently.
