Nope - (being blunt) Remember that that isolcpus is theoretically set properly
by grub2.
1) start linuxcnc 2.5.0 from command line.
f50mm g1 x0 y0 z0
top shows:
cpu0 64% system 35% idle
cpu1 100% idle.
2) taskset 0x0002 linuxcnc
f50mm g1 x0 y0 z0
top shows:
cpu0 70% user 27% idle.
cpu1 65% system 33% idle

I'm going to run some tests tonight with linuxcnc tasksetted to cpu1.
Wonder, though, why cpu0 70% user space processing is happening with taskset
set? Maybe a tight loop in there waiting for something to happen.
I'll report back tomorrow on how well my machine runs tests using an explicit
taskset.
