Shib IdP v.3.3.0 memory usage

[Cantor, Scott]

The snapshot of 3.3 I've been running in production is about 1100MB and it doesn't include probably the majority of the new code that I would think would contribute to memory use, like the Metrics library and those dependencies. I think it's closer to what's in 3.2.1 than to 3.3-final (e.g. the same Spring version as 3.2.1).

I guess being Jetty maybe it's not a good comparison, but it seems to rule out a lot of the things I would immediately think about.
