	Well, this makes me wonder if you set flags in ELF files, what

	this files would seem to have more of a risk factor.

	From my point of view, there are too many things that need to
	be considered and need to be taken into account for adding such
	a feature to mainstream DragonFly code.

	Although, once I get the ``Patch Page'' up on the website, we
	can put this work up there, just like how I suggested for the
	ACPI patchset.  At least this way, it gets exposure, more
	testing and we don't have to risk unwanted integration into
	the DragonFly CVS.
