queue mtime on Solaris 8

I currently have a script which stats the ldm queue to find out if it has
been modified. This script is on a Solaris 7 x86 and sparc boxes and works
great, but when we moved it to a Solaris 8 x86 or sparc box it fails. It
appears the mtime is not updated on writes for mmap'ed files, as it once
was.

Solaris 8 x86 Host stat returns:
mtime = 1045780379 atime = 1045836118 ctime = 1045780379

Solaris 7 x86 Host stat returns:
mtime = 1045836983 atime = 1045836983 ctime = 1045534243

Solaris 8 Sparc Host stat returns:
mtime = 1045699609 atime = 1045802101 ctime = 1045699609

Solaris 7 Sparc Host stat returns:
mtime = 1045836874 atime = 1045836874 ctime = 1045836874

Is this a bug in Solaris 8? I know Linux says atime on a mmaped file may or
may not be updated, but there is nothing like that in the Solaris man pages.

Any help would be greatly appreciated.
