Bug: exception loading nodes for Ole object

[GoogleCodeExporter]

What steps will reproduce the problem?
1. submit let browser = new System.Forms.WebBrowser();; to fsi
2. expand "browser" root node in fseye

What is the expected output? What do you see instead?

Expect normal behavior, but instead get prompted with an unhandled exception 
dialog: 

System.Threading.ThreadStateException: Current thread must be set to single 
thread apartment (STA) mode before OLE calls can be made. Ensure that your Main 
function has STAThreadAttribute marked on it.

Please use labels and text to provide additional information.

Nodes are loaded asynchronously and in parallel using F#'s async feature. i.e. 
nodes are being loaded on threads from a thread pool which cannot be set to 
STAThreadAttribute 
(http://social.msdn.microsoft.com/forums/en-US/Vsexpressvb/thread/a23a47f8-efd2-
4117-b107-6757254d8e27). However, we may be able to test whether specific 
values are IOleObjects 
(http://msdn.microsoft.com/en-us/library/windows/desktop/dd542709(v=vs.85).aspx)
 and create special STAThreads for those rarer cases (continue using the thread 
pool for most cases).

Workaround.

In the example given, submitting browser;; to fsi before attempting to expand 
the browser node in fseye will prevent this bug from manifesting.
