Just a heads up that I'll be idle (well more idle than currently) for the 
next 3 weeks (I'll still read email) but I've got other commitments coming up 
(I'm actually in a play that starts in a fortnight, so I just don't have the 
time to sit down and code.)

This is just in case people are wondering what happened to my ideas on pmap, 
I've been looking at how our pmap works, certainly something that stands out 
is that our pmap_remove is really really slow as it loops through the whole 
of the 16k L1 table looking for ptp's to free off, so I might take the i386 
approach of using a uvm_object and allocating them into that, so that there's 
just a linked list to walk and free off entries, I'll probably also work on 
then getting ptp's also freed off as ptp's are no longer used. I'd also like 
to get growkernel in place as well, as this saves having the logic for 
allocating kernel ptp's all over the place.

Oh for 36hr days :)

Cheers,
Chris
