History
Ken Smith 0fac1537a2 It was noticed that we do not change a file's access time when it gets 
executed.  This appears to violate most of the UNIX-ish standards.
One example quote from:

  http://www.opengroup.org/onlinepubs/009695399/functions/exec.html

    Upon successful completion, the exec functions shall mark for update
    the st_atime field of the file. If an exec function failed but was
    able to locate the process image file, whether the st_atime field is
    marked for update is unspecified. Should the exec function succeed,
    the process image file shall be considered to have been opened with
    open().

This appears to take care of it for ufs filesystems, doing the necessary
sanity checks (read-only filesystem, etc) without violating any other
standards (setting atime for any open appears to be allowed in any standards
I could find).
