Subject: [PATCH] 2008-01-11  Tatsuhiro Tsujikawa  <tujikawa at rednoah dot
 com>

	Added Piece::getFirstMissingBlockIndexWithoutLock() and it is
called
	from PiecedSegment's ctor.
	Previously Piece::getAllMissingBlockIndexes() is called from
	PiecedSegment() but it is rather expensive since only first
element is
	used.
	* src/PiecedSegment.cc
	* src/Piece.{h, cc}
