Hmm.. since this code will be so Classpath-specific, perhaps Classpath
should provide the code to handle it.

E.g., Classpath could provide a new class VMDirectBuffer that contained
methods which would be invoked by the VM itself in order to implement
GetDirectBufferAddress() and  GetDirectBufferCapacity(). After all,
the logic to retrieve this information is "known" to Classpath,
not to the VM (i.e., the VM would have to be written to a specific
version of Classpath, assumptions about java.nio object fields, etc).

Does this sound feasible? I'm new to this NIO stuff so this idea might be
random and completely wrong.
