https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=187594 --- Comment #23 from karl@denninger.net --- Status -- still grinning, still doing what it's supposed to on my fairly-heavily loaded production machine..... This machine has a large Postgres database running on it and has 19Gb of RAM wired at the present time. Are there any further comments from the reviewers on integration into the tree for general distribution?
