Since I don't know what ZAPsavepage() does & requires, I don't know  
if the problem is the register_shutdown_function or not.

I went to the program code I thought I'd used  
register_shutdown_function in to grab a working example for you --  
turns out it had caused problems because UpdatePage was taking far  
too long, so I had turned it off to debug (I was getting a hung  
process on my laptop -- I'm glad I never made it live!  I'd have a  
mad ISP...).  I got everything working smoothly and forgot to  
reinstate it. :P  So everything is working smoothly without  
register_shutdown_function on my program.  I had fixed UpdatePage  
hanging by temporarily resetting:

	$EditFunctions = array( 'ReplaceOnSave','SaveAttributes',  
'PostPage','AutoCreateTargets');

-- in other words I removed a bunch of functions from the queue of  
items that UpdatePage was running when it created a page (most  
noticably the ones that update RecentChanges pages and check for  
NotifyPosts).  Then forgot to make it write the pages AFTER the  
browser refresh.  Page creation happens so much faster now, I didn't  
notice that I'd forgotten to put it in the background again.  The  
downside is that people can add 100s or 1000s of pages using this  
function, and there's no RecentChanges logged.
