Memory leak?

[oeway]

Hi Thomas,
The ScriptEditor is awesome, and I like script in Python.
Recently, I found some memory issue when using the the scriptEditor. The following steps will reproduce the problem:
1 Set "Max memory" option in Preferences into some small value, for example 128M.
2 Open a sequence to eat up almost all the memory.
3 Open "Script Editor", put the following python code and run it:

from icy.main import Icy
from icy.sequence import SequenceUtil
sequence = Icy.getMainInterface().getFocusedSequence()
print somethingNoneExist

And, a error will be thrown.
4 Close the sequence and the Script Editor
5 open the sequence again, memory will overflow.

If we do the similar thing in Javascript, memory won't overflow. But if you don't close the Script Editor in step 4, it will overflow too.

This means the script engine won't clean the memory when error occured in script. I've tried to read the code, but I can't find a way to do that. I hope you can fix this, it bothered me a lot.
