You should instead investigate your system and try figuring out why it is loosing performance.  Try reverting to an older version of nVidia's drivers.  If the problem goes away, report the problem to nVidia.

Are you sure it is X that is growing without bound?  Do you have exact numbers for memory usage over time?
