[vtkusers] vtkImageReslice & threads

[David Gobbi]

Hi Alexandre,

There are no known problems with vtkImageReslice and threads at the
current point in time.  We use it on 2X PC systems and a 4X IRIX
system regularly.  Any additional info that you could give me regarding
the circumstances of the crash would be valuable.  I'll look into this
in January when I'm back at work.
