I should have a chance to look at your threading issues this weekend,

Hi,
I was wondering if you had any time looking at this problem with
creating/accessing variables from different
threads (I attached the code that reproduces the problem again).
It seems that a variable created by an evaluation on Thread A is not
visible if you try to access
the variable from Thread B.
