SVN rev 213044 on 2010-09-23 01:24:33Z by delphij
In the past gunzip(1) write()'s after each inflate return. This is
not optimal from a performance standpoint since the write buffer is
not necessarily be filled up when the inflate rountine reached the
end of input buffer and it's not the end of file.
This problem gets uncovered by trying to pipe gunzip -c output to
a GEOM device directly, which enforces the writes be multiple of
sector size.
