Thanks for reviewing.

We could split this test into 3 if you think its worth it. For now, it 
needs to be run by jtreg and will be run 3 times, each with a different 
policy. To keep it simple it attempts to walk test.src (an alternative 
would have been to create a file tree, perhaps in the tmp dir and 
corresponding policy files). As the default policy grants reads access 
to the current directory then it would otherwise cause the "denyAll" and 
"grantTopOnly" tests to fail.
