The cvs 1.12.12 (or later) version of CVS provides
a commitid. The NEWS file for 1.12.12 said this:

| * CVS creates a unique session id that gets
|   written to the RCS files during import and
|   commit. When committing several files at once,
|   they all get the same 'commitid'. The commitid
|   becomes visible with log and status commands,
|   and is derived and compatible with the cvsnt
|   project.

The value of the commitid for 1.12.12 was not as
good as it should have been, so the value in
1.12.13 has been improved to go from a hex value
to a base62 value with more bits in it.

A patch for RCS to create and manipulate the same
commitid is available in the
contrib/rcs-5.7-commitid.patch file in the cvs
1.12.13 distribution or may be downloaded from the
CVS repository on savannah.nongnu.org.

Yes, the current methodod of determining a "change
set id" would need to consider a comparison of the
log message for any revisions committed by the
same user within a 'few seconds' of the same time.
(At worst case, there would be a one-second drift
across all of the directories committed in a
single commit for the repository.)

The CVSNT folks added commitid to their fork of
CVS in late 2002. I believe it was first released
with CVSNT 2.0.15.

        Enjoy!
