I really don't recommend setting this in any release.  There is
currently a bug with binding kernel threads that causes unrelated
threads to be unnecessarily bound to CPUs.  In the specific case of
net.isr.bindthreads this will cause(among others) the softclock
threads to all be bound to the same CPU, which may well obviate any
performance increase from binding the netisr threads.
