ChangeSet@1.2309.1.12, 2006-09-12 15:42:13+02:00, guilhem@gbichot3.local +14 -0
  Fixing problems I identified in my auto_increment work pushed in July
  (as part of the auto_increment cleanup of WL #3146; ...
The problem is in that show binlog events in indeterministic, row events can be compressed,
so that 2 seconds original delay does not guard from inconsistency.

We syncronize test's current inserted rows counter with system insert delayed thread
per each query.

From another side there is no requirement for binlog to be event per row and then 
to verify if binlog has recorded what was recently inserted is better
via reading from it instead of 'show binlog events'.
