I realize my first post was pretty vague. I have managed to locate the
allocation that is giving me trouble. It is in IceContainer.cpp at
line 126:

	// Get some bytes for new entries
	udword*	NewEntries = new udword[mMaxNbEntries];

Even after I have destroyed my ODE world, collision space, and all
trimesh data, this allocation is still hanging around. It appears to
belong to a Container that belongs to a SphereCollider that belongs to
a trimesh. Everything looks like it should be cleaned up properly when
the trimesh is destroyed; I am still investigating.

The rest of my original post follows.
