    Despite the numerous reports of current problems I'm running 5.2-CURRENT for
    12 days now without a glitch. Tested overnight with 2 buildworlds running
    with -j8. It's a 2 processor Xeon server with 4BSD scheduler. Just my .02
    euro.

    Another thing is bothering me. In top I see:

CPU states: 16.2% user,  0.0% nice,  2.5% system,  1.0% interrupt, 80.3% idle
Mem: 254M Active, 605M Inact, 254M Wired, 16K Cache, 112M Buf, 2622M Free
Swap: 4096M Total, 4096M Free

  PID USERNAME PRI NICE   SIZE    RES STATE  C   TIME   WCPU    CPU COMMAND
37033 mysql     20    0   265M   178M kserel 0 610:59 124.37% 124.37% mysqld


    MySQLd is running with libpthread and can go up to 400% without
    significantly afecting the idle percentage shown by top. I don't see how I
    could fit 400% into 20% on those two suckers, therefore I ask :)
