Description
A customer pointed out a concern that our VM was mapping our C-heap allocation
as all read-write-execute. We do require "executable" access for our
CodeCache, but should not require it for the rest of the C-heap.

                                    

Comments
EVALUATION

Fix in progress.  Set execute bit on only the code cache.
