Frankly, if

 stat a
 sleep 2
 whatever

does not behave the same as

 sleep 2
 stat a
 whatever

I'm tempted to blame the file system.  `stat a' must cause some
timestamp to be updated.  What filesystem is this?  Is it
mounted with some funky option?  (I see Solaris has a dfratime
option to defer atime updates on UFS; and your case let me
feel like mtime updates was differed until the next stat.)
