There has never bee a way to avoid jvm init time, because this var was
never enabled. :-)

We considered adding in some more knobs for this, but now that a typical
instance will have only 1 jvm running in it (using threads that are
shared between apps), the jvm startup will only happen 1x. So we didn't
consider it a big deal.
