[the words 'kernel' and 'time' in the subject were sufficient to squeeze
this one past my insanely strict linux-kernel filter. Best reply to me
directly if you want to guarantee I see it.]
[[linux-kernel community update -- i'm hard at work hacking a
java-to-silicon compiler, which is why i've vanished from net.life.
i'll be back eventually, don't y'all worry. Say hi to Linus for me. =) ]]
