I don't think this is the appropriate place for such a patch.  By all
means, disable escape analysis in Sun's builds but I don't think this
is appropriate for being pulled into OpenJDK6 as well.  It obviously
shouldn't be the default, but if users want to turn on a feature
that's there in the codebase, they should be able to.
