Oh.  I wonder if our configuration is really that unusual---we run a
Java management agent on most machines, and given that it doesn't do
anything most of the time, a reduced JVM size is quite interesting.
(For this particular application, -Xint -XX:+UseSerialGC isn't that bad,
even the TLS encryption has acceptable speed.)
