The addin is "mainly" single-threaded - Outlook always calls us from the
same thread.  The only time a second thread is used is by the "training" or
"filtering" dialogs.  If "training" is running, then this thread will be
updating the database - however, in that case, the dialog is up, which is
modal, so there is no way the other thread could be doing a training
operation.

The passage you quoted doesn't rule out the possibility that this error
could occur even if only one thread is writing, but another is reading.  If
that is a problem, then yes, we would hit it :)
