Strikes me as something you might want to use in code that is orientated 
towards working with chunks of data of a possibly fixed maximum size (i.e., a 
chunk orientated steaming environment).

The readv call gives you the ability to fill a series of chunks (e.g., from a 
free chunk list or something) with one call into the kernel.  This could be a 
significant improvement from being forced to fill them individually.

Cheers!  -Tyson
