That's strange. Perhaps the TLB geometry is biased in some way? I simply
can't understand where the fudge comes from, in that case.

I'd like to believe. Who has the best example of a non-trivial
image-based GUI running in the iTools framework to try? Of course, my 5
year old video card fails to impress iTools, which typically crash my
X-Windows server after about 2 minutes of noodling. I can't exactly blame
that on ITTVIS, but needless to say, it makes me less willing to drink the
koolaid.
