Actually, it made not be pre6.  I patched the kernel per some thread
on LKML a few days before, but had not had the opportunity to reboot
and run it until pre6.  The patch was :


--- linux/mm/page_alloc.c.~1~	Tue Mar 20 15:05:46 2001
+++ linux/mm/page_alloc.c	Sat Apr 21 19:01:47 2001

 		if (gfp_mask & __GFP_WAIT) {
 			memory_pressure++;
 			try_to_free_pages(gfp_mask);
-			wakeup_bdflush(0);
 			goto try_again;
 		}
 	}


It would make more sense that the above change was responsible for the
improvement.
