Imports
com.kenai.jffi.Closure, org.jruby.Ruby, org.jruby.ext.ffi.AllocatedDirectMemoryIO, .InvalidMemoryIO, java.util.concurrent.atomic.AtomicBoolean
An implementation of MemoryIO that throws exceptions on any attempt to read/write the callback memory area (which is code). This also keeps the callback alive via the handle member, as long as this CallbackMemoryIO instance is contained in a valid Callback pointer.
