Interestingly, for MMR, this does not result in any data loss, as the 
changes are replicated w/o problem:

MMR node taking writes:

Apr  6 21:56:47 ldap01 slapd[34514]: slap_queue_csn: queueing 0x10bfcc80 
20160407025647.107497Z#000000#003#000000

Apr  6 21:56:47 ldap01 slapd[34514]: syncprov_sendresp: to=004, 
cookie=rid=102,sid=003

MMR node receiving writes:

Apr  6 21:56:47 ldap02 slapd[61570]: do_syncrep2: rid=102 
cookie=rid=102,sid=003
Apr  6 21:56:47 ldap02 slapd[61570]: slap_queue_csn: queueing 0x80ee240

Apr  6 21:56:47 ldap02 slapd[61570]: syncprov_matchops: skipping original

Apr  6 21:56:47 ldap02 slapd[61570]: slap_graduate_commit_csn: removing 
0x420c2c0 20160407025647.107497Z#000000#003#000000
Apr  6 21:56:47 ldap02 slapd[61570]: slap_graduate_commit_csn: removing 
0x80ee240 20160407025647.107497Z#000000#003#000000

So the change is still correctly replicated to the replicating MMR node.
