Looks good.

Except for one thing:
  As I read Inside Mac, the ReleaseResource invalidates the handle. I
  interpret this as meaning that the master pointer is invalidated as
  well.

  So, this sequence would work for two unrelated programs (or program
  parts) only if each GetResource returns a handle with a separate
  master pointer. I don't think that happens (at least it shouldn't!).

  I admit I've never tried this. I'm reluctant to try anything that doesn't
  look iron clad and guaranteed. This doesn't.
