   I do this all of the time, it's not a huge speed gain, but it does
   remove the overhead of a filesystem write for every fopen(). 

   I've not run into any problems with this and have used it with
   various software ( PostgreSQL, MySQL, Sendmail, mod_perl, vanilla
   Apache, etc, etc. ) on both ext2 and ext3. 

   I doubt it will cause you a problem.  Think about this way, when was
   the last time "last accessed time" was useful to software you were
   writing? :) It's almost always last modified that you need/want.
