If you are doing fallback calculations in a 6MB buffer that is 1,500
pages. Accessing all of this effectively flushes the data cache. Once
you are done with it you probably don't want those pages in the cache
anyway.

I wouldn't count on it flushing anything

I meant flushes out everything except the 1,500 pages you just
accessed. Since you don't want those pages any more a total cache
flush shouldn't make a difference, you don't want any of these pages
in the cache anyway.
