> Please find attached a code review of BlockTokenIdentifier.
> The only real change is using an explicit StringBuilder instead of an implicit one so
that the internal buffer may be set more appropriately and checking for zero-length string
instead of comparing to an empty string.  The relatively small default buffer of 16 bytes
would need to be expanded several times to fit the incoming string.
