> Over in Apache Log4j-land, we are working on a GC-free logging epic.
> We try hard to generate as few objects as possible. Right now, we create one CSVPrinter
per logging event to create a CSV line for that event.
> In order to get the best memory profile and performance, this ticket proposes to refactor
the CSVPrinter and CSVFormat objects to allow a subset of print operations directly from the
CSVFormat object.
> I tested this patch with the Log4j Git master and it works.
