title: SharePoint 2010 event listener - SPItemEventReceiver with multithreading
body: <p>I have an event handler dll that implements <code>SPItemEventReceiver</code>.  I like to run a background thread in this dll.  The events are passed on to this background thread for processing so that the event handling methods won't block.  SharePoint 2010 loads the dll but the thread does not start.  I am not able to use the <code>ThreadPool</code> class as well.  Is this a restriction imposed by SharePoint on external event handlers?  How can I work around this?</p>
