Comment(by simonmar):

 Stephen - we do have Linux platforms that return different addresses for
 exec and writable: SE Linux on Fedora, for example.  The two addresses
 refer to the same memory, which is why you can write to one and read from
 the other.

 I haven't looked at your patch in detail, but I am also wondering why we
 need an extra hash table.  When I wrote this code it was intended to
 support the write and exec addresses being different.  We had a bug in
 this that was discovered recently, see #7629, and with the fix it is
 working fine.
