> I think drill will benefit from mode of operation that is called "quiescent" in some
databases. 
> From IBM Informix server documentation:
> {code}
> Change gracefully from online to quiescent mode
> Take the database server gracefully from online mode to quiescent mode to restrict access
to the database server without interrupting current processing. After you perform this task,
the database server sets a flag that prevents new sessions from gaining access to the database
server. The current sessions are allowed to finish processing. After you initiate the mode
change, it cannot be canceled. During the mode change from online to quiescent, the database
server is considered to be in Shutdown mode.
> {code}
> This is different from shutdown, when processes are terminated.
