Description

Here is my interpretation of what we have discussed recently:

Document the pattern that should be used by executables that run art in a thread as part of a broader application and investigate whether existing artdaq/ds50daq executables are currently following this pattern. The goal is to have "signal handling within artdaq/ds50daq executables consistent and sufficient to lead to an orderly shutdown of the executables (including any art threads) as quickly as possible". [quote from an email from Chris]

This is connected to Issue #4353 in the ds50daq project.
