The maximum file size is probably a property of the underlying filesystem,
so I don't think it should be explicitly defined as a value like 2.1E9;
especially since this value is inaccurate, because it isn't equal to the
value 2^31, which is probably what was meant.

I think that instead of trying to guess a value that would be correct for
many filesystems, but obviously wrong for others, we should just remove the
explicit size.

Not necessarily.  It's what kern.maxfilesperproc says.  On my CURRENT
system that is a little lower than kern.maxfiles:

# gothmog:/home/giorgos$ sysctl -a | grep files
# kern.maxfiles: 8072
# kern.maxfilesperproc: 7264

Can you help us identify them?
