(room) side effects

[allender@aristotle.ils.nwu.edu (Allender )]

Hi,

We are trying to uncover the nature of a weird side-effect.  We
have a large image that was built using MCL 2.0.1, Wood and Oodles
of Utils.  The image was created on a Quadra 800.  The image
runs well enough on the 800 and on my FX.  It often runs just
fine on our Quadra 950.  Recently, the image (which has not
been altered) started acting "cranky" on the Quadra 950.  

If I type (room) before starting up my multimedia program, it runs
fine.  If I don't, I get gworld allocation errors.

Is there any reasonable explanation (hardware or software) for
this behavior?
