> Note: The atime of a file is supposed to change whenever
the data blocks of a file are being read. This can be
costly performancewise when an appliation regularly
accesses a very large number of files or directories. Some
Unix filesystems can be mounted with atime updates disabled
to increase the performance of such applications; USENET
news spools are a common example. On such filesystems
this function will be useless.
