fix CLEANALLRUV and winsync - consumer update race condition - mem frag debugging
Ticket 450 - CLEANALLRUV task gets stuck on winsync replication agreement
Ticket 386 - large memory growth with ldapmodify(heap fragmentation)
this patch doesn't fix the bug - it allows us to experiment with
different values of mxfast
Ticket #374 - consumer can go into total update mode for no reason
