Steven, you hit the nail on the head.

It took quite a while to recompile in its brain-damaged state but in 
this case the physician really did heal itself!

And, yes, Ian, the performance is now, indeed, on par with the unxenifed 
kernel.

I have only 1G so I will have to apportion it carefully; I'll keep your

Now the real fun starts :)

Thanks to all,
Mike Wright
