This will DRASTICALLY decrease the memory footprint of the nnrpd process. Pre patching, 120 readers would fill ram and 200Mb of swap. Post patching, I've gone past 150 readers and still had 150Mb swap left.... I'm running inn1.4unoff4 with about 6 full inbound feeds and 3 or 4 partials, although for all but 3 of those I send out more than I get. Also, more disks==good. CCD works fine. The only downside is when a drive dies, there is no recovering the ccd'd partition. However, news isn't THAT valuable.
