Hi!

If you haven't noticed: last week I've pushed a change that enabled semi-join optimization flags by default, i.e. now the default @@optimizer_swich value
has:

 semijoin=on
 firstmatch=on
 loosescan=on

Philip: if you have any testing planned for "after semi-join optimizations are
enabled by default", now it's time to do them.
