Attachment: Proposed fix

nsISupportsArray which is an array of nsIImportMailboxDescriptor is generated in importing thread, so we don't have to dispatch to the main thread.

Proposed fix

the problem is that these classes really aren't thread-safe, so making the isupports thread-safe isn't sufficient, other than to quiet the warnings which are really legitimate warnings.

Fixing the thread-safety assertions might well involve rewriting the import code not to run on its own thread. Fixing this particular assertion probably involves figuring out a way of getting a thread-safe array or enumerator out of the mailnews backend.
