[as discussed earlier today on IRC]
The verifier can throws an invalid MethodAccessException when doing its access
checks.

This happens when:
System.Xml.Linq.XHashtable`1/XHashtableState:TryAdd (TValue,TValue&) (flags
134)
(from MS System.Xml.Linq.dll Silverlight 2 SDK)

calls:
System.Threading.Interlocked:CompareExchange<System.Xml.Linq.XHashtable`1/XHashtableState/Entry<TValue>[]>
(System.Xml.Linq.XHashtable`1/XHashtableState/Entry<TValue>[]&,System.Xml.Linq.XHashtable`1/XHashtableState/Entry<TValue>[],System.Xml.Linq.XHashtable`1/XHashtableState/Entry<TValue>[])
(flags 150)

This behavior can be seen on:
