Issue with grep -i (on i386 only?)

Hi, attached a little test script for grep's -i performance. I tried a few different machines and the 64-bit 7.2 machine I could steal doesn't seem to be affected and out performs pcregrep. On i386 machines, grep -i is significantly slower: i386, 7.2-STABLE of Sep 8, load averages: 0.00, 0.02, 0

Mesh networking

Anyone interested in Mesh networking might want to have a look at http://meshcom.com/en/products/meshdriver/ We have started to use the mesh driver (ok, on voyage linux). A port should not be difficult, especially the userland daemon. It's dependencies on Linux syscalls are minimal.
