	By the way, what kind of performance improvements are we looking
	at with this new code (including stage-3) in place?

	Also, just a little snooping around, I think the
	textvp_fullpath() function can made a little generic so it is
	applicable to other cases.  I have a patch lurking around for
	this somewhere, I will e-mail it to you by Friday.

	I haven't gone through the whole patch in detail, as I am
	feeling kinda sleepy. ;-)
