Until the very latest Matlab release, Matlab had no way to do the
equivalent of unwind_protect.  Now, they have of course chosen to
implement something that sort of does the same thing, but in a
completely different way.  There has been some discussion of this
feature on the lists already, if you are intersted in helping out.
