The original message there suggested it was particularly valuable when 
working with a somewhat broken kernel that was handling multiple 
simultaenous reads badly.  I think the idea here is that if you've got an 
OS that handles that situation well, then the fadvise calls don't help 
much.  But having them in there does improve the odds that the kernel will 
do the right thing with the sequential reads.
