I wonder if there's any interest in a ClassLoader that will close JAR
files once they haven't been used in quite some time (like a day or so).
If you have a bunch of libraries in your webapp and they all get nearly
fully-loaded on startup, or after a few requests, then you could save a
bunch of file descriptors by closing those files.
