Just recently finished checking. For the collection of Linux hosts I
have access to, the probe results are the same regardless of the choice
of set or get. I agree 100% that "get" is a safer probe.

This changes whatever affinity might have been set before this check,
for example by a (smart, don't know if such exists now) batch system.
I haven't checked if it's possible, but I think that a similar
solution based on sched_getaffinity would be much better, as this
would not disturb the current settings.
Paul and I were discussing this earlier (off list). He was
investigating doing the same check with sched_getaffinity() -- I
don't know if he has finished checking into that already.
