 csc generates an initobj !!ServiceType, while gmcs generates an ldnull, and
 PEVerify flags this as invalid IL.

+Hmm.  That's strange.  The 'ldnull' verifiability rule says:
+The ldnull instruction is always verifiable, and produces a value that
+verification considers compatible with any other reference type.
+Does that mean that verification doesn't take constraints into account?
