"no really, be quiet" mode for ping{,6}

Sometimes I want ping to be quiet. Not quiet in the "only show me headers" way that the original author thought was cute, but in the "don't show me anything" way, so cron doesn't spam me with useless crap. So, in honor of that, here is a patch to add -Q to ping and ping6. OK? Index: sbin/ping/

Push kernel stacks and malloc memory high

We might not ever do this, but at the moment as we go into bigmem dma handling it is nice if we trigger bugs earlier rather than later. This triggers some bugs, some of which are easy to fix. Run it please if you can and report problems in details. Index: kern_fork.c

Hi, Now that I've disallowed swapping to vnd's the purpose of vnd (vs svnd) is suspect, it serves no purpose other then providing a different way of doing what svnd does (which imo, isn't even better). So, nuke vnds (keep svnds though!). This will make svndXn the same as vndXn etc. The idea is t
