You know, in a multiuser environment there is alot of work types.
some of them more important and need fast response, fast insert, fast
update(urgent tasks).
if there is alot of user with running heavy but none-time-critical
queries, they can create a DISC I/O bottleneck on system.
my goal is to detain this user with CPU operations and to deffer their
DISK I/O operations.
