If enabled (is on by default), MySQL will honor the
@code{DELAY_KEY_WRITE} option for @code{CREATE TABLE}. This means that the
key buffer for tables with this option will not get flushed on every
index update, but only when a table is closed. This will speed up
writes on keys a lot, but you should add automatic checking of all tables
with @code{myisamchk --fast --force} if you use this. Note that if you
start @code{mysqld} with the @code{--delay-key-write-for-all-tables}
option this means that all tables will be treated as if they were
created with the @code{delay_key_write} option. You can clear this flag
