iirc the idea was to read the sysdb entry first to make sure we have the
latest data from sysdb. Because of the asynchronous nature of the
request it might be possible that another request already updated the
sysdb entry. To avoid unneeded writes we try to compare the new data
with the latest data we know. This is led by the assumption that
reading from sysdb is a lot cheaper then writing to it.

bye,
Sumit
