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}
