We used to allow enabling “fork”, but since it’s never safe to fork
the JVM we ultimately removed that ability entirely. There are other
ways to do this, though…I’m sure others on the list will have
suggestions, and I would help you dig if you can’t find anything.

FWIW, I’ve always daemonized Java processes using something like
nohup, so I’m on the “spit and baling wire” side of things.

I noticed this after I sent my previous mail. Where is this coming
from? JRuby does not ship anything under lib/ruby/site_ruby/1.9.1. Can
you explain what this is?
