Yes and yes. I load code into the subject image for remote
messaging, and use a VM which keeps track of which methods have been
run, and with a garbage collector that doesn't mark methods which
haven't been run. From a remote image, I invoke the GC in the subject
image and all but about 300k of it falls away in one fell swoop.
