[vtkusers] Resource Leak with VTK + BCB6

[Mathieu Malaterre]

Nick,

	I feel a bit you pain. But:

1. You didn't mention the invisible timerlog management, which make a 
huge difference. And this problem doesn't look easy to me.

2. It's only a memory leak... a real OS ;) doesn't need it.

my 2 cents
