+Summary: ViewState fails on ListBox with lots of items
+
+Description of Problem:
+
+Viewstate intermittently fails to load when given a large ListBox
+
+
+Steps to reproduce the problem:
+1. Create an autopostback ListBox with many items (in my case, 10000)
+2. Click on a few different list items
+
+
+Actual Results:
+
+An exception is thrown.  I haven't spotted any real pattern as to when this
+occurs
+
+System.IO.EndOfStreamException: Failed to read past end of stream.
