:What about doing the changes on a branch with the understanding that

:This sounds odd at first glance, but it means that others are forced

:Anybody that's not confident to be able to merge into the smp branch
:will simply be in the same position - merge or hold off. They'd also
:be just as likely to break the smp work with their commits as if the
:smp work was done in HEAD.
Won't work. Too many files are being messed with.

The changes to i386/ are substantial. The changes to kern are
mid-sized. The changes to most other places are minor.
This is with the legacy spl code still left intact in most places.
Every file in the entire sys tree is going to change when we start
ripping spl's out for real. At the moment I only have to rip them
out of the sysconsole path and in i386.
