Umm, in case you didn't know, the extent patch which is the primary issue
of discussion here (not the whole 64-bit clean changes though) were run
for MILLIONS of hours under very high IO load on the largest computer
systems in the world for the last year or so. It is easy to get millions
of hours of usage if there are thousands of servers running this code...

Yes, I have no doubt there will be bugs in the code because the usage
pattern is different for different environments, but we aren't advocating
the inclusion of something major like this that was just written
yesterday in someone's basement.

Cheers, Andreas
