should, so we end up emitting a bunch of warnings.
Currently corlib generates 490 of these warnings, i am not sure if it
is even worth fixing, so for now am making this feature available only
at warning level 4 (the default is 2).

+I assume you're doing the check on a per-file basis, right?
+You'll get very few (or none) warnings if you keep record of the
+namespaces as global to the compilation run instead of on a per-file
+basis. The location of the using statement would be only used to
+report the warning, not to check that _in that file_ the using
+statement was needed (since neither csc warns about this, right? We
+issue the warning only because it costs compile time).
+So, for example, if a random file in corlib has:
+but it doesn't use types from that namespace in that file, no warning
+is flagged, because there are other files in the corlib build that
+reference that namespace.
