Note: I've been testing without my hack for the sleep-gets-stuck
problem for some days, mostly in usefdt mode.

I've finally had pmac_thermal end up stuck-sleeping during a
from-scratch buildworld buildkernel on the 2-socket/1-core-each
G5 PowerMac11,2 running in usefdt mode.

So the improvement in mp_machdep.c for better matching the Time
Base Registers across CPUs/cores/threads still is not enough to
guarantee lack of some sleeps getting stuck.

(Without the hack I've no recording of about how far out of order
the problem times where.)

(I may end up running with my hack generally.)
