I was also starting to look at this problem.  For what it's worth,
here's a client program that I used to generate a lot of multixact
members.  The patch seems to work correctly so far: as the offset
approached wraparound, I saw the warnings first with appropriate OID
and members remaining, and then I was blocked from creating new
multixacts.

Best regards,
