    Maybe I'm using the wrong terminology.  What I mean to say is that
    Intel caches, under most conditions, will flush dirty elements in
    their caches to main memory very quickly.  i.e. unlike, say, the old 
    68040 cache which leaves dirty cache lines in the cache almost
    indefinitely.  The intel caches implement a write ordering constraint
    and a FIFO to deal with dirty data.

    Yes, I guess that would be write-back rather then write-through,
    But not delayed-write.
