Resolve FAQ:

Don't report a JavaScript warning ("Disconnected") until the OperationCallback
has been executed 10 times with the user offline. This gives the executing
script ample time to recognize the disconnected state and exit gracefully.
Script that do not check/notice that the user has disconnected will still be
auto-terminated (by default) and this warning will still be logged in those
cases. The value 10 was picked at random and appears to work fine.
