It appears that a rough rule of thumb yields 16 * nCPU as the optimal
thread number. I've some code that tries to detect the number of CPUs,
we could use it to choose the default if not set in slapd.conf. I'm
considering a rough algorithm like "threads = min( 16 * nCPU, 64 )".
Would this qulify for inclusion?
