[vtkusers] VTK in a multi-threaded program

[David Cole]

You are definitely not going crazy. The really, really rather foul 
thing, that frustrates me all the time, is when I must do some VTK 
operation which takes significant time (on the order of seconds or 
minutes, rather than the typical fraction of a second) ... and then it 
makes the GUI completely unresponsive until the operation is done.

I spend rather a lot of my time making sure that everything I do that's 
VTK-based is at interactive speeds as much as possible to absolutely 
minimize the user pain associated with this.

Pushing long operations completely into a separate non-GUI thread would 
be absolutely fantastic. I look forward to the day when such a thing 
becomes possible.
