What a cool idea. Basically keeping an open file descriptor so that
information about the file is pinned in the kernel. Some antique systems
might complain that someone already has the file open, but using input
redirection should force a read open that doesn't really do anything except
fetch up the needed info.
After Oracle sees this, I wonder how long before they add adaptive
observation of switch times and execute an open a while before they need to
switch so they won't have to wait for file info when they need it.
Holy cow. That is from April 2002 and this is the first time I've noticed
it.

I'm not familiar with that, or at least, I can't recall it.
And ixora.com.au seems to be down at the moment.
What is the premise?
