I just wanted to make a general suggestion:
When we move forward with updating the VTK version VisIt uses - we 
should definitely try check for leaks and resolve them as part of the 
I am sure we are responsible for a lot of them - but we are using an 
older version of VTK & I wouldn't be surprised if some of them exist in 
the library.
After we upgrade the version of vtk we use should have a clean bill of 
health, and we can hunt those down.
Also it would be useful for us to adopt this type of checking across our 
nightly test suite.
