LoaderLock was detected ???

For some time I have seen this weird error that seemed to pop up out of nowhere. When debugging a solution in Visual Studio 2005 I would occasionally get a "Loader Lock was detected. Attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang". I sort of ignored the error for a few days since I couldn't connect it to anything I did. Well, it only took 2 minutes on Google to find out that the offender is ITunes 7.1. (see here and here) I am using an IPod Nano to listen to podcasts while commuting to work. As a morning ritual I plug in my new Nano and ITunes starts automatically. I usually let ITunes run in the background for a little while downloading new shows before shutting it down to save precious CPU cycles for VS which is a slow beast. I still don't have a clue what causes this.
Anyone?
