> AvroUtils.checkTypeName (which is called a LOT) is always creating a 
> StringBuilder and doing a bunch of appends and toString's even if the 
> condition is true.   It's not using a proper format  string and varargs for 
> the parameters.  This results in a lot of extra objects being created when 
> using Avro.
