Subject: SP Patchset #2 up (one minor bug fix)
Sender: owner-freebsd-smp@FreeBSD.ORG
Precedence: bulk
X-Loop: FreeBSD.org

    I fixed a minor race condition in the Mutex code in tsleep().  It was
    releasing the interrupt mask (spl0()) too early and allowing an interrupt
    in which might attempt to wake the id up before the process could 
    actually be queued to it, resulting in a forever-blocked process.

    Apart from that, the patch set appears to be reasonably stable.
