    Ok, excellent.  I figured out why my I/O rate was still high -- I
    also hadn't turned on softupdates for /var/tmp, but it didn't make
    much of a difference since I use -pipe in my compiler options so
    I am still hanging on around 5-7% too.

    That's still significant, but not as fun a number as the first one :-).

    I am coordinating one more patch set with Mike that makes sigprocmask
    and the core copyout function MP safe (so both copyin and copyout are
    MP safe).  Copyout is basically MP safe already, sigprocmask
    needed only minor adjustments.  Then I'm going to turn the code loose 
    in 5.0 and, in a week or two, backport it to 4.0.  Then it will be up to
    the rest of the community to push the MP lock further, I don't have
    as much time on my hands as I used to :-).
