Is it true that File.split() is faster than FasterCSV?  Yeah, I bet it  
is.  Likely reasons are:

* It's written in C
* It doesn't handle all types of CSV data, so it has less work to do

To give some examples, you split code doesn't parse this valid CSV data:

   no,quotes

Or this:

   "embedded
newlines"

Hope that explains things a bit.
