    Disallow leaving more than maxmsg voicemails.
    This is a possibility because our previous method assumed that no messages are
    left in parallel, which is not a safe assumption.  Due to the vmu structure
    duplication, it was necessary to track in-process messages via a separate
    structure.  If at some point, we switch vmu to an ao2-reference-counted
    structure, which would eliminate the prior noted duplication of structures,
    then we could incorporate this new in-process structure directly into vmu.
