Mono.Runtime.GetDisplayName() is commented as:

    // Should not be removed intended for external use
    // Safe to be called using reflection
    // Format is undefined only for use as a string for reporting

It should be safe to rely on this method, though not necessarily to rely
on the semantics/format of this method.

Mono.Runtime can't be public because it's in mscorlib.dll, and we need
to provide the same public API as .NET's mscorlib.dll (otherwise you
could compile against Mono and the resulting app wouldn't run on .NET).

You should check that `t' is not null before using it, as it will be
null when running on .NET.  Otherwise, that looks correct.
