Well, I'm answering my own question for the benefit of all :)

This appears to be legacy behavior so that old CM pascal programs that
depend on this behavior won't break. Although anyone who depends on this
sort of behavior should have both their legs broken :)

The program calling the XL must have the directives. It doesn't matter if
the XL has them -- the new/dispose are being called in the context of the
program, not the XL.
 
Perhaps this should go in the 3K FAQ.
