Hmm, if the platform doesn't support setting of cpu affinity you should
report an error here and return failure. Otherwise the user will think
that the affinity was set successfully and when he tries to read it
(code below) he/she gets incorrect value.

Okay, this is fair enough, but you have to fail in the setting call so
that this function doesn't lie to the user.
