Does an Activity-managed Cursor invoke requery() on another thread?

Question

From within an Activity I query my database from an AsyncTask, and I pass the result Cursor to startManagingCursor(). From the docs, a managed cursor will automatically invoke requery() when an activity is restarted.

My question is, is requery() invoked from a background thread? If not and this runs on the UI thread and the query takes a long time to return this could cause a Application Not Responding dialog, right?
