   @ashb The setup works like this (I am @overbryd, just a different account.)
   
   * There are dynamic DAGs that are part of the repository, and that gets 
pulled in regularly with a side-car container on the scheduler.
   * The worker has an init container that pulls the latest state of the 
repository.
   * Secondly I have DAGs that are built (very quickly) based on database query 
results.
   
   This scenario opens up the following edge cases/problems:
   
   * A DAG can go missing, after it has been queued when the entry is removed 
from the database, rare but happens.
   * A DAG can go missing, after it has been queued when a git push happens, 
which change the DAGs, before the worker started.
