I have a question and a comments.  First, does killproc on linux wait
for the process to die?  I ask because slapd can take a long time to
write out it's data and you shouldn't run ldbmcat on a live database.
Second, our "private" slave also thinks it is a master, and so creates
a relog.  We have a cron job that saves the replog each hour for a
week.  With a weeks worth of ldifs and relogs, we can recreate the
database at any point in the week.  This offers us protection from
(possibly malicious) non-crash data corruption.
