Solarmutex Deadlock when Closing Calc which contains functions with XVolatileResult return values

[anwen]

Eike, I agree with you that the listeners are destroyed during document
close. I observed it in my log file. However, the worker thread is running
asynchronously if not calling the listeners' modified function. How can it
know that the document is closed, stop calling the modified function, and
quit itself gracefully. So in the first post, I asked if there is a signal
which announces that the document is closed.

Please correct me if there is something wrong with my thought.

Best,
Wendi
