> 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.
