not until such time as we are certain that it has no further need to 
grow. That size was chosen for a reason -- we expected it to grow, but 
were not sure. It may grow again, if a bug fix is needed. I don't want 
to drop it to, e.g., 35k at this point.

What we can do, however, when we are sure it is as big as it will get, 
is drop the padding to 48k or so. But we need to leave room for the 
inevitable bug fix that may grow it past 35k.

I would like to make a request: let's slow down just a bit on all these 
changes. I think we're rushing some of this stuff, and we just got 
buildrom stabilized. You have to be very, very careful when shipping a 
bios, and I'm growing uncomfortable with the pace of changes from just 
today. We have to leave room for future bug fixes.
