We're using JRuby in an app server, and the app server needs to keep track of the sizes of running applications within it while running for monitoring, to detect leaks, and to limit resources if necessary. What I'm looking for is a way to write a method in Java that returns the approximate size of an org.jruby.Ruby instance (and, if possible the total size of all the Ruby objects in ObjectSpace).
It sounds like there's nothing like that available within JRuby itself (nor do I see anything like it in my brief poking around in the source code).
