Add locking to the source AuxContainer when making a copy of it (!34600) · Merge requests · atlas / athena

Marcin Nowak requested to merge mnowak/athena:lock.auxcont.when.copy into master Jul 09, 2020

ATEAM-624 and ATEAM-626 show job failures that we suspect were caused by modifying AuxSelection at the same time another thread tried to make a copy of the same AuxContainer.
