Hi Jeff,

I had just made a backup - and thought I'd give your patch a
whirl on my little  Dual PII 600Mhz / 1GB Ram.

Done overnight :

 - Multiple buildkernel and buildworld with -j 4, -j 6  and -j 10
 - a few installkernel (and reboot) as well as one installworld.
 - an incremental Backup with Bacula while buildworld was running.

No incidents.

I have not done any performance testing, not verified if there is
indeed less contention on the Giant Lock - subjectively it appears
that Giant shows in top much less than before .. but obviously
that is not really representative.

Thanks a lot & keep up the good work !
