The lack of a static method to get the thread ID is a feature ;-).
There is no "main thread" limitation like in VTK or Qt.  ITK can be
used successfully in a multi-threaded context.  For instance, it is
possible to run ITK filters spawned by threads created by OpenMP --
each one of these filters will spawn their own threads.

This is a nagging issue that I have not been able to find out the root
cause of with a few cursory looks -- please let me know if you have an
idea!
