this will cause better computation speed for single- and multi-core; there are enhancements that will speed up old and slow machines as well as multi-core CPUs. Indexing of surrogates has been speed up from 4000 PPM to over 20000 PPM on a simple dual core office computer. Since the enhancements are mostly in core routines, the hack should also speed up search performance. git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6276 6c8d7289-2bf4-0310-a012-ef5d649a1542
