Sorry, I have never said that we will have concurrent replace & update in
the near future. With MyISAM and HEAP it would introduce the problems
of dirty reads and we are not yet prepared to allow the use of
optional dirty reads..
We are however working on adding a new table handler that will
supports transactions. This handler will have smaller granularity on
locks, but if you do a GROUP BY on everything, you will still get
something similar to table locks. (This is common on most systems that
uses page locking).
As the above is done by just modifying a new class, this will not make
the 3.23 server more instable (it may only be a bit more instable IF
you use this new table type...)
