The size of the data "cvs rlog" produces is roughtly O(N*M) where N is the # of files in the directory and M is the amount of changes. So even when a delta is small, on a large repository this can produce significant amount of data. Use of ByteArrayOutputStream causes a large spike that can kill a VM, so spill the data over to disk if we are getting large output.
