ministat example for comparing performance

This is mostly a reminder to myself how to get and use FreeBSD's ministat for performance comparisons. This somewhat useless example shows that -server is apparently the default flag for java these days. Note: you have to strip out some FreeBSD-isms to get it to compile on Linux.
