Pretty intersting, I just ran this and noticed it (the diff between
queue and gettimeofday time) drifts about 70 usecs per second. Is this
normal expected behaviour, or another reason to hate the day I decided to buy
a X2 CPU?

P.S.: ANyone got any hard facts on the TSC SMP issues? 2.6.15
is definitely worse for me than 2.6.14, things that used to work just dont anymore.
