Beta 6.5

>>>     In February, we start beta on 6.5, which will have multi-version
>>>     concurrency control, thanks to Vadim.  For those of you who did not
like
>>>     our table-level locking, you will be really surprised.  Not only do
we
>>>     have row-level locking, we have something even better.  In row-level
>>>     locking, a reader can not read a row that is locked by a writer.  In
the
>>>     6.5 locking system, READERS ARE NEVER BLOCKED, and writers block
only if
>>>     they try to modify a _row_ that another writer has modified and not
>>>     committed.
>>>
>>>     This is a major feature, better than many commercial databases.
There
>>>     is also no running out of locks like commercial systems, because the
>>>     transaction ids take care of that.  A true NUMERIC type with
>>>     user-specified precision is also planned for 6.5, thanks to Jan.

Bruce, this sounds great.
