Hi, Russell!

I think "concurrent" already has a clear meaning, at least in MariaDB -
operations are done "concurrently" if they're executed truly in
parallel, usually in different threads. For example, both MyISAM and
InnoDB allow concurrent SELECTs, but only InnoDB allows concurrent UPDATEs.

I considered simultaneous_assign, as a slightly shorter alternative to
simultaneous_assignment. But it looked somewhat unnatural to me.

Still, this is the case when I happily yield to the opinion of a
documentation writer :) If you think that simultaneous_assign looks
just fine, I'll use it.
