The `B_EXECUTE_AREA` flag for `create_area()` and friends is currently
private (though we should change that eventually). However, the
<sys/mman.h> API already allows creation of/changing protection to
executable memory ranges.

Well, that's a bit exaggerated. It is certainly thinkable that the API is
used in an attack vector, but using it is made significantly more
difficult due to DEP and ASLR.
