Ok, here's the problem:

Let's say I have a file named "/tmp/obj.off"...
I send the following command to geomview:

(new-geometry obj < "/tmp/obj.off")


now, let's say that outside geomview I do this:

cp /u/gcg/ngrap/data/geom/dodec.off /tmp/obj.off


This overwrites what was in /tmp/obj.off before.
Now if I send the following command to geomview:

(new-geometry anotherobj < "/tmp/obj.off")


what I would expect is that geomview will now have two objects,
obj = (what was in the old obj.off)
anotherobj = (what is in the new obj.off ... in this case a dodecahedron)

But what happens? ... BOTH obj AND anotherobj become what is in the new
obj.off. This is a TERRIBLE feature of geomview and has been known about
for quite some time, so why hasn't it been fixed??? We cannot let GEOMs be
inextricably linked to files in the unix filesystem. The only way to work
around this is to come up with a unique file name every time you want to load
a new object into geomview which is not a good solution. Can this be fixed
sometime soon?
