Running our application under a limited user throws this exception at weird
times and we cannot find any information on it:

Object reference not set to an instance of an object.  
   at System.Runtime.InteropServices.Marshal.ReleaseComObject(Object o)
   at System.Management.Instrumentation.MetaDataInfo.Finalize()

The only common denominator seems to be it hits when we're running multiple
threads.

We're using 1.1 with SP1.  We tried running both debug and release builds
with no luck.  Tried setting tracing to max to get some idea of where it
was happening but no luck.  Does anyone know what's happening?

Thanks,
Aaron
