AS: With kernel 2.4.10 we have seen
that Linus Torvalds has preferred Arcangeli's VM to yours. What do
you think of his decision? And why has he made that?
RvR: It was a strange situation, first Linus
ignores bugfixes by me and Alan for almost a year, then he
complains we "didn't send" him the bugfixes and he replaces the VM
of course. The new VM has better performance than the old VM for
typical desktop systems ... but it fails horribly on more systems
than the old VM. Redhat, for example, cannot ship the new VM in
their distribution because it'll just fall apart for the database
servers, some of their users run at least now my code is gone I no
longer have to work together with Linus, which is a good thing
AS: Why is it a good thing?
RvR: With Linus out of the way, I can make a
good VM. I no longer have to worry about what Linus likes or
doesn't like. This is mostly important for intermediary code, where
some of the "ingredients" to a VM are in place and others aren't
yet in place. Such code can look ugly or pointless if you don't
have the time to look at the design for a few days, so Linus tends
to remove it ... even though it is needed to continue with
