Re: [visad] Thread interrupt to prevent OutOfMemoryError

Hi Marius,

DisplayImpl is an ActionImpl so I believe if you'd like to stop the display 
transformation you can make use of it's `stop` method.  But I suspect that 
you're running into issues reading the data in which case you'll have to stop 
whatever thread you're reading the netcdf file from.
