I wonder if there might be something else at play here.  I don't have
"noac" or "actimeo" or any of the other ac* options specified.  "grep
ac /proc/mounts" turns up nothing.  If I explicitly mount an NFS
directory with "-o noac", the noac and ac*=0 options show up clearly
in /proc/mounts.  Yet I still have this 1-second delay after moving to
a new item in the recorded programs list.
