2009-10-21md5sum, sha*sum, sum: line-buffer the printed checksumsPádraig Brady
* src/md5sum.c (main): Set stdout to line buffered mode to ensure parallel running instances don't intersperse their output. This adds 5% to the run time in the worst case of many zero length files, or 2% with standard file sizes. * src/sum.c (main): Likewise. * tests/misc/md5sum-parallel: New test for atomic output. * tests/Makefile.am: Reference it. * NEWS: Mention the fix
