This serves as a good starting point.  I converted the 
ClassLoader.NativeLibrary to use it:
http://cr.openjdk.java.net/~mchung/jdk10/webrevs/8164512/webrev-cleanable/

Looks reasonably well and probably some other improvement I could do.  I 
use createResource rather than createLongResource which is specialized 
for an address. We should check out panama how this plays out.

I think it would be useful to iterate on several more use cases and it 
would be better to separate this RFE from JDK-8185582 so that we can 
explore with its own pace.
