 I suspect you were using 'cpuset -c -l N -p <PID>' rather than
 'cpuset -l N -p <PID>' in which case this is working as designed.  When you 
 use '-c', you change the mask of the global cpuset that the process belongs 
 to, not the mask that is private to the process itself.
 
 The cpuminer bug referenced was exactly due to this (it was using 
 CPU_WHICH_CPUSET incorrectly which is identical to using cpuset -c)
