Review comment:
That was my first implementation, but that messed up with the current
query outputs (qfiles).
I have tried to throw the ReCompileException (CBOException at that time),
and then decide based on the exception. The problem arisen when I had to
extract and rethrow the cause of the CBOException if the exception was fatal to
provide the same outputs. I have chickened out from that path to keep the
existing logic in place.
