I did a similar thing. I took the rserv trigger "as is," but rewrote the
replication support code. What I eventually did was write a "snapshot daemon"
which created snapshot files. Then a "slave daemon" which would check the last
snapshot applied and apply all the snapshots, in order, as needed. One would
run one of these daemons per slave server.
