michael@0:   // gives rise to a situation that wouldn't really happen in practice.

michael@0:   // A more serious issues is that we don't/can't test the Xray wrapper path,

michael@0:   // structured clone don't force a parent in PreCreate, and so we _can't_
michael@0:   // have security wrappers around them (we get a new XPCWN in each
michael@0:   // compartment). Since the case can't happen, we can't write tests for it.
michael@0:   // But when it can happen (ie, we fix PreCreate for File, FileList, Blob, etc),
michael@0:   // we want tests right away, because this stuff is very security-sensitive.
