[krbdev.mit.edu #7695] krb5-1.11.3/1.10.6 - full resync may fail and still result in ulog being updated

[Greg Hudson via RT]

In the absence of hierarchical iprop, I can't come up with a scenario 
where current_dump_sno_in_ulog() erroneously returns true.  Can you 
outline a series of operations on the master which would cause it to do 
so?
