Fine, if the metadata request was originating at the browser - but I'm
trying to create a request from PHP (to generate the page which will
then make an AJAX request). My PHP script needs to know the metadata
in order to set up the page - its just a matter of convenience to use
the same script for metadata and data.

? debug_backtrace() and register_tick_function() seem to operate
without corrupting the stack frame.
