Oops, I didn't get the "readahead" option description
quite right in the last post. The default read ahead
is 1, which does result in "rsize * 2", since there is
the read + 1 readahead.

"rsize * 16" would actually be for the option "readahead=15"
and for "readahead=16" the calculation would be "rsize * 17".

However, the example was otherwise ok, I think? rick
