--- Comment #13 from Mark Hiner <hinerm at gmail.com> ---
It's definitely an issue with our implementation of the jython script language.
The python environment is not cleaned up after running a script - and in fact
there is code that relies on the environment not being cleaned up.

You can hack it right now and effectively "force" the scope of the variables to
be respected, by explicitly setting them to None before your script ends.

e.g.:

   inputIp = inputImp.getProcessor()
   #... do some stuff with the IP...
   inputIp = None

will ensure the image processor doesn't stick around. But that is, of course,
terrible.

I've been looking at options for cleaning up the python environment[1] but the
timing of when to do so is tricky.

I'll keep trying...
