[PyMOL] System freezes in cause of memory abuse

Hi!

I'm working with big structures and even bigger trajectories. When I try
to load a trajectory, pymol takes the full 2GB RAM and freezes my PC
(ubuntu 7.10/gnome/core 2 duo/2 GB RAM). The only way out is pulling the
plug. :-(

My Question:
Is there a possibility to reduce the memory used by pymol?
The "nice" command did not work, because it just reduces the available
CPU time for pymol and not the available memory.

Greetings
Christian.
