SVN rev 184385 on 2008-10-28 03:26:25Z by peter
After a machine has been up for a bit more than 20 days with HZ=1000,
"ticks" goes negative. This breaks the signed comparison in softclock.
This causes sleep() to never wake up, tcp to stop, etc etc. This is
bad(TM). Use the SEQ_LT() method from tcp's sequence number comparisons.
