It means the disk must continue spinning and, e.g., will
continue to draw power from a laptop battery to do so, even when
the system is functionally idle.
I think that's a more general problem. It would be nice if all
updates to atime/mtime/ctime could be buffered in memory (not
committed to stable storage) until either the disk happens to be
spinning anyway, or the amount of memory "wasted" in buffering the
updates is too large, or the updates are forced using a mechanism
like fsync(2) or sync(2).
I even want syslogd's writes to /var/log/messages to be buffered
until the disk happens to be spinning anyway.
