kern.timecounter.choice: TSC-low(1000) i8254(0) HPET(950)
switching the machine from TSC_low to ACPI-fast fixes the problem.
in 8.x it used to default to ACPI
but I used to switch it to "TSC" to get better performance.
I wonder why TSC-low is now bad to use..
maybe the TSCs are not as well sychronised as they were in 8.x?
maybe the pthreads code didn't get the memo about changing timers?
