Clean Host

I've been tracking down a funky memory issue as of late, and it's down to some of the caching being done on one of my FarCry HTML objects. Essentially, the PS Old Gen fills up, and during the course of trying to run a GC on it, one of my four CPU cores just goes AWOL. I'll kill the thread in htop, and the Resin watchdog service will automagically fire back up, and within about 3 minutes we're good to go.

After having something concrete to pass to team Daemon, I'm truly thrilled to have gotten a response back in just a few hours time. Turns out, Daemon has already been working on the objectBroker caching abilities. They now keep a watch on memory use, and automatically start clearing objects out of cache should memory start to go downhill.

I've been watching FusionReactor off and on for the past 3 hours, and I think this fix has nailed the problem. Before, a GC wouldn't bring memory down past 70% or so. Now, it's coming back down to 50%. Combine that with FusionReactor watching for super long running requests, and I think I can now go back to my customer and tell them we can expect no more major slow downs or memory issues. I love open source communities!

If you're looking for this fix, you can find it in both the p610 branch and p600 branch
